COURT HEARS CLAIMS MAN SCREAMED: ‘I’M GOING TO MURDER YOUR SON’

first_imgLetterkenny Court.A man who was accused of assault has denied any wrong-doing when he appeared at Letterkenny District Court. Jason O’Connor, 24, with an address at Railway Avenue, Killygordon was accused of assaulting Seamus Duffy in the early hours of the 2nd of March 2013. Seamus Duffy told the court that he and his wife Amanda were awoken by banging and kicking at their front door at around 3am.His wife Amanda went to the front door and found an incensed and irate Jason O’Connor going berserk asking where their son Jason Duffy was.She said he was screaming: “Where is your son? I’m going to f***ing murder your son and cut his throat.”O’Connor was told by Amanda, that Jason wasn’t in the house, and she said he had replied: “I’m going to cut his throat when he comes back.”In his evidence to the court Mr Duffy said that when he appeared at the front door O’Connor lunged at him and the pair began to wrestle.Mr Duffy said he managed to get him into a headlock, and revealed to the court he had only recently undergone an operation on his chest.During the scuffle Mr Duffy said that O’Connor repeatedly punched him in the chest saying, “Is this where you had your f***ing operation?The pair were eventually separated by Mr Duffy’s wife Amanda and Linda Linton, mother of Jason O’Connor’s partner Leanne Linton.It was then that Mr Duffy and his wife Amanda realised there was a fire at the property of O’Connor.They saw the local fire brigade and members of the Gardaí attending to the scene of the blaze.O’Connor believed that Jason Duffy started the fire, but Jason Duffy wasn’t in the area that evening.Solicitor for the defendant Donough Cleary cross-examined Mr Duffy’s evidence in court, and compared it to the statement he gave Gardaí just a few days after the alleged incident.He asked Mr Duffy was Jason O’Connor carrying something in his hand, he said he was but wasn’t sure what it was.Mr Duffy said: “I’m not sure what it was, it looked like a knife, but I’m not 100% certain what it was, it could’ve been a stick.”However, Mr Donough Cleary pointed out that in Mr Duffy’s original statement he was anything but vague regarding whether O’Connor was carrying an implement or not.In his statement Mr Duffy had said O’Connor was wielding a kitchen knife, about 6 or 7 inches long, and that it had a black handle.Mr Cleary also said that Jason O’Connor’s girlfriend Leanne Linton and her mother Linda Linton saw Mr Duffy pursue O’Connor down the path and hit him with a hurley.Mr Duffy denied doing that and said it was completely untrue and that the incident never took place.When asked why he had a hurley in his house, Mr Duffy snapped back: “There’s a hurley in every house in Killygordon.”In his evidence to the court Jason O’Connor admitted he thought Jason Duffy had started the fire to his shed and was absolutely fuming and marched down to his property to see was he in.He admitted banging and kicking the door and asking where was Jason Duffy, when he was told by Amanda Duffy he wasn’t in he turned and walked back towards his own property.However, O’Connor claimed that Mr Duffy struck him with a hurley on the shoulder, O’Connor turned and took a swipe at Duffy before the two began to grapple and wrestle in the garden.In his summary Judge Denis McLaughlin said there had been two very conflicting accounts of what happened that evening.He said, “There are two very conflicting accounts of what happened being presented here today, but I’m not satisfied beyond reasonable doubt.“If Mr Duffy hadn’t changed his account regarding the knife, it could’ve had serious implications for Mr O’Connor if he was found guilty.“However, the fact he initially said he was wielding a large kitchen knife with a dark handle, to now not knowing what it was has created doubt, and that’s why I hereby announce that this case is dismissed.”COURT HEARS CLAIMS MAN SCREAMED: ‘I’M GOING TO MURDER YOUR SON’ was last modified: November 12th, 2014 by Mark ForkerShare this:Click to share on Facebook (Opens in new window)Click to share on Twitter (Opens in new window)Click to share on LinkedIn (Opens in new window)Click to share on Reddit (Opens in new window)Click to share on Pocket (Opens in new window)Click to share on Telegram (Opens in new window)Click to share on WhatsApp (Opens in new window)Click to share on Skype (Opens in new window)Click to print (Opens in new window) Tags:courtsJason O’ConnorKillygordonnewsSeamus Duffylast_img read more

Tilt-A-World: Another Constraint on Habitability

first_imgDid you ever ride a Tilt-A-Whirl, one of those cheap carnival rides that makes you dizzy and sick?  Our planet would be like that (in slow motion) if its inclination were out of control.  Without tilt stability, a new study reveals, we wouldn’t be sick, we’d be dead, or never alive in the first place.   It’s not enough to be in the Habitable Zone.  Would-be inhabited planets need to avoid a new problem, called “tilt erosion.”The new constraint on habitability is described in an article by Adam Hadhazy on NASA’s Astrobiology Magazine, “Loss of Planetary Tilt Could Doom Alien Life.”  Astronomers considering the factors needed to sustain life already knew that inclination was important.  They knew that it provides for alternating seasons, distributing the temperate zones so that the equator is not eternally hot and the high latitudes eternally frozen.  They also knew that red dwarf stars (the majority of stars), with their narrower habitable zones closer in, tend to tidally lock one face of a planet toward its star, dramatically reducing its habitable real estate (2/09/2006).The new study by René Heller, a postdoctoral research associate at the Leibniz Institute for Astrophysics in Potsdam, Germany, shows that stable inclination is far more important for life than previously assumed.  Cheerful astrobiologists envisioning life everywhere are going to have to worry about this new constraint; “The findings do not bode well for planets residing in the habitable, or ‘Goldilocks’ zones around red stars smaller than the Sun,” the article said.  Here’s a summary of Heller’s findings and the implications:Time limit:  “According to computer simulations, red dwarf stars quickly erase the axial tilt of habitable, Earth-like exoplanets. This temperature-moderating tilt is nullified in such a short time that life may never have a chance to get going.”Far out:  Habitable planets around sun-like stars suffer far less tilt erosion.  So far, so good – provided they have at least 5 degrees of tilt.  If not, watch out:Gasping for air:  “In theory, bands of habitability in temperate, mid-latitude zones could persist. In a worst-case scenario, however, the entire atmosphere of a zero-obliquity planet could collapse, Heller said. Gases might evaporate into space around the planet’s blazing middle and freeze to the ground in the bleak north and south.  Life, had it ever emerged, would be stopped dead in its tracks.”Zero tolerance:  All planets suffer tilt erosion, including Earth.  “Over time, this mechanism forces the planet into a zero-obliquity equilibrium.”  This limits the time available for life to originate and persist: “The length of a window of significant obliquity could be critical for the development of life.”Narrowing and harrowing:  Most stars have too short an obliquity window: “For relatively cool, dim stars with less than half the Sun’s mass, the obliquity window becomes quite narrow.”Life stopwatch:  Assuming that evolution needs more than a billion years for life to originate and evolve up to sentience, it’s never going to happen on worlds around stars less than 90% the sun’s mass.  Red dwarfs have an obliquity window of about 100 million years; stars with 90% the sun’s mass might have a billion years before it’s too late, and the planet is forced to zero obliquity (see points 3 and 4).  Heller said, “We found that extrasolar terrestrial planets in the habitable zone of low-mass stars lose their primordial obliquities on time scales much shorter than life required to evolve on Earth.”Size doesn’t matter:  Won’t larger planets fare better?  Sorry; “The obliquities for ‘super-Earths’ – worlds several to 10 times the mass of the Earth – would also rapidly vanish around red dwarfs.”Lockout:  “To make matters worse,” the article continued, tidal locking gets added to tilt erosion.  One side becomes locked to face the star forever.  “That side can become superheated and sterilized while the dark half of the planet enters a permanent, frozen night.”Jupiter’s wrath:  A habitable planet too close to a gas giant suffers its gravitational blows.  Thank God Earth is farther from Jupiter than Mars.  “Hulking Jupiter wreaks havoc with the Red Planet’s obliquity, causing it to vary by perhaps as much as 60 degrees over the course of a million years, Heller said. Those disturbances lead to big swings in global temperatures and glacier cover, and on more habitable worlds that sort of climatic chaos could spell the end for life.”Lucky moon?  Our moon helps keep Earth’s obliquity stable for long periods, but that’s partly because we orbit a rare star  “Yet big moons might not be a saving grace for habitable-zone, terrestrial worlds around red dwarfs. The habitable planet’s necessary close proximity to a dim star could destabilize lunar orbits, said Caleb Scharf, director of Columbia University’s multidisciplinary Astrobiology Center, who was not involved in Heller’s research.”Overall, the article on NASA’s prime astrobiology website sounds pretty pessimistic for astrobiology (a science without a subject).  Obliquity is coming into view as a far more critical factor for habitability than previously realized.  Caleb Scharf, director of Columbia University’s multidisciplinary Astrobiology Center, who was not involved in Heller’s research, got off the Tilt-A-World onto solid ground when he said, “obliquity can certainly end up being the critical lynchpin of determining whether or not any part of a planet could be considered habitable.”  All we know is that conditions are pretty darn good on the spinning globe on which we stand.If you haven’t experienced a Tilt-A-Whirl, somebody recorded a stomach-eye view on YouTube.  Enjoy.  Ponder Earth on that kind of trajectory.In The Privileged Planet documentary, Dr. Bijan Nemati (JPL) explained the combined probability of some 20 different factors needed to support life, using conservative values of 1 in 10 for each, at a thousandth of a trillionth.  That makes another habitable planet unlikely in the Milky Way or local group of galaxies.  This new factor might just lower the probability to make Earth unique in the local supercluster of galaxies, if not the whole universe.  Let’s tally up the habitable zones astrobiologists have told us about:Galactic Habitable Zone, where a star must be located (09/29/2009);Circumstellar Habitable Zone, the right radius from the star (10/08/2010);Continuously Habitable Zone, because too much variety can be lethal (07/21/2007);Temporal Habitable Zone, because habitable zones do not last forever (10/27/2008);Chemical and Thermodynamic Habitable Zone, where water can be liquid (12/30/2003);Ultraviolet Habitable Zone, free from deadly radiation (08/15/2006);Tidal Habitable Zone, which rules out most stars that are small (02/26/2011).Stable Obliquity Habitable Zone (this entry)Some of these probably overlap: for instance, a red dwarf will fail on the last two points due to the same forces eroding obliquity and tidally locking the planet’s rotation; a red dwarf will also subject its planet to flares and UV.  It is still very clear, though, that getting all these factors just right requires winning a cosmic lottery.  You can have an earth-like planet with a good moon orbiting a sun-like star, but if it is outside the Galactic Habitable Zone, no dice.  Or you can have all the right combinations except a star that is less than 90% the sun’s mass, and tilt erosion will kick in, given enough time, to erase life before (using evolutionary assumptions), sentient beings could evolve.  It’s like a combination lock; close enough is not good enough.Note that the list of Habitable Zone factors ignores other requirements, like water, the right atmosphere, the right crustal composition, a global magnetic field, plate tectonics, the right moon at the right distance, and more.  A planet could win the Habitable Zone lottery and still be lifeless if too volcanic (like Io), or shrouded in carbon dioxide and sulfuric acid (like Venus), or lacking surface carbon (see 05/21/2011).Let’s face it: either we are pretty darn lucky, or Earth was designed for life, as the Creator spoke through the prophets (Isaiah 45:18).  If you take the former view (luck), you have said good-bye to science.  Why?  Because sheer dumb luck is none other than the Stuff Happens Law (9/15/2008, 9/22/2009), the law of nature for science quitters (“Why is there life on Earth?  Stuff happens”).  It’s a hand-waving answer that provides no useful information or understanding.When you combine extremely low probability (see our online book) with functional information (a planet that supports sentient life), you get intelligent design science.  When you combine that with consciousness and intelligence, you get philosophy.  When you combine that with revelation from the Creator, you get all the necessary and sufficient evidence you need to understand yourself, the world, and the universe.  What’s the problem?  Why would anyone wish to resist the only answer that makes sense of the world?  Stop riding the Tilt-A-World theory of evolution, and stand on the solid rock (Matthew 7:13-29).(Visited 31 times, 1 visits today)FacebookTwitterPinterestSave分享0last_img read more

Ohio’s Crop Progress — July 17, 2017

first_imgShare Facebook Twitter Google + LinkedIn Pinterest Continued wet weather with heavy downpour events caused many fields to be lost to standing water and has stalled harvest, according to Cheryl Turner, Ohio State Statistician with the USDA’s National Agricultural Statistics Service. There were 1.9 days suitable for fieldwork for the week ending July 16th. Northwest and Central Ohio were drenched by heavy storms. Major rains fell in the vicinity of Hancock, Hardin, Seneca and Wyandot counties on already saturated soils. The Blanchard River near Findlay crested at 16.5 feet, which was three feet above major flood stage. Critical cropland drainage networks were overwhelmed and corn and soybean fields were inundated with water. Reports of Sclerotinia led many growers to scout fields for disease. Winter wheat is still in the fields as wet field conditions has prohibited harvest. Excessive moisture created concerns over head sprout. Pasture and range conditions changed little despite the rains. Farmers delayed manure applications and bailing of straw. Other fieldwork was minimal and limited to mainly spraying.July 17, 2017 Crop Progresslast_img read more

Fundamentals of Psychrometrics, Part 2

first_imgSpecific volume vNo Dew point temperature TDPYes Dry bulb temperatureThis one’s easy. It’s the temperature we’re talking about when we use that word without any descriptors in front. It’s how hot or cold the air is. It can be measured in a number of ways and is one of the three independent quantities we need to define a psychrometric state point.One definition of temperature is that it’s a measure of the kinetic energy of the molecules. It’s not the best definition (because of things like quantum mechanics and zero point energy), but it’s fine for this discussion. And that brings us back to air, and the molecules it comprises. Recall that air — moist air — is made of dry air and water vapor. When we measure temperature of the air, it includes both components, so the dry bulb temperature of the air applies to both. They’re equal.On the psych chart: Dry bulb temperature is shown on the horizontal axis along the bottom.Wet bulb temperatureActually, that should be plural since there are two types of wet bulb temperature: what we measure with a psychrometer and the thermodynamic wet bulb temperature. Fortunately, if you use the psychrometer properly, the two numbers are very close. It’s sometimes called the temperature of evaporation because you measure it by wrapping a wet material around the bulb of a thermometer, swinging the thermometer in the air at a certain rate, and then recording the temperature reading. It’s lower than the dry bulb temperature because swinging the wet bulb thermometer causes some of the water to evaporate, taking some heat away.Well, I say it’s lower, but it’s not always. There’s one condition where the wet bulb and dry bulb temperatures are equal. Know what it is? Saturation. When the space (not the air) can’t hold any more water vapor molecules without some of them condensing into liquid water, the wet bulb temperature equals the dry bulb temperature.On the psych chart: Wet bulb temperature lines run diagonally downward from the saturation curve toward the right.Dew point temperatureThis one’s similar to wet bulb temperature but in the opposite direction. Wet bulb is the temperature of evaporation. Dew point is the temperature of condensation. If you take a volume of air and cool it down with adding or removing water vapor, you eventually reach a temperature where condensation occurs. You’ve reached the dew point, or saturation.Here’s one of my favorite questions to ask students about dew point: If you have a volume of air and don’t change the water vapor concentration, what happens to the dew point when you increase (or decrease) the dry bulb temperature? Do you know? (The answer is below.)And here’s another one for you: When are the wet bulb and dew point temperatures equal? As with wet bulb and dry bulb, they’re equal only at saturation. And that means all three are equal at that point. As soon as you get away from saturation, however, the three temperatures diverge.On the psych chart: Dew point temperatures are horizontal lines. The value is usually shown at the saturation curve.Barometric pressureThis one’s pretty easy. It’s just atmospheric pressure. It’s helpful to think about it as a bunch of collisions. If you put those air molecules in a container, they’ll hit the walls of that container and push outward on them. The force per unit area they exert on the walls is the pressure of the air.Here on earth, barometric pressure results from the weight of all the air above the volume we’re studying. Since there’s more air above Savannah than above Salt Lake City, the barometric pressure is higher in the former city. In fact, altitude is an equivalent quantity because if we know it, we can easily determine the barometric pressure. Yes, it does vary with weather, but those variations are small compared to the changes with altitude.Then there are the two components. Remember our mixture: Air is a combination of dry air and water vapor, so some of that barometric pressure comes from the dry air component, some from the water vapor. Together, they add up to equal the barometric pressure.pbar = pDA + pWVThis is an important relation used to do a lot of psychrometric calculations.On the psych chart: Barometric pressure isn’t actually shown as a variable on the chart. It’s used to calculate a particular chart. If you’re more than a thousand feet from sea level, you’ll need to make sure you use the correct chart because it affects the values of some of the psychrometric quantities.Water vapor pressureWell, we just saw that this quantity is one part of the total, or barometric, pressure. It’s an important quantity, too. It determines which way water vapor moves: from higher vapor pressure to lower vapor pressure. It’s also used in determining a couple of important quantities I’ll discuss below.I know what you’re thinking. You’re thinking, this would be a great time to discuss a pot of water with a closed lid over the top. And you’re right, because that’ll give us a another way to understand this thing called saturation.So that pot of water is sitting there. If you leave it long enough and don’t change anything, the air above the water will become saturated. It will reach its maximum vapor pressure… at that temperature. If you lower the temperature, some of the water vapor will condense out. If you raise the temperature, more water vapor will evaporate into the space above the liquid. As it turns out, the saturation vapor pressure depends only on the temperature.On the psych chart: Lines of constant vapor pressure would run horizontally if it were shown.Relative humidityAh, relative humidity. It’s measurable. It’s talked about all the time. It’s not as easy to understand as you may think. One incorrect way of thinking about it, perpetuated by many well-meaning weather reporters, is that it’s the percentage of water vapor in the air compared to how much the air can hold.There’s more than one thing wrong with that statement. First, the air doesn’t determine how much water vapor can be in a space. Second, it’s not the ratio of the mass or concentration of water vapor.The actual definition is this:RH = 100 x pWV / pWVSBoth vapor pressures in the equation occur at the same dry bulb temperature. That means you go straight upward from your state point to the saturation curve to find the two pressures. (Most psych charts don’t show vapor pressures, though.)On the psych chart: Relative humidity shows up as curves through the chart. As the dry bulb temperature increases, the RH curves sweep upward from the bottom left. The 100% RH curve is the same as the saturation curve.Specific enthalpyEnthalpy was the bane of my undergrad thermodynamics studies. That was probably because I had to look it up in steam tables rather than learn the psychrometric chart, but let’s say a little bit about this mysterious quantity in the hope that it won’t be your bane.First, there’s no tidy way to explain the concept of enthalpy. It’s sometimes said to be a combination of the sensible and latent heat content of a volume of air, and that’s part of it. But there’s another part that comes into play sometimes, and that’s the work done on the air. Here’s the equation that defines specific enthalpy:h = u + pvThe equation says that specific enthalpy equals internal energy plus the product of the pressure and the specific volume (defined below). We can’t calculate absolute specific enthalpies, so keep in mind that only differences in specific enthalpy matter.That idea that enthalpy is a combination of sensible and latent heat is from the first term in the equation. Changes in temperature or in the amount of water vapor result in changes in internal energy. If the pressure or volume also change, work is being done on or by the system, and that’s part of the enthalpy changes, too.What can you do with enthalpy? When you’re putting a volume of air through certain psychrometric processes, as you do in air conditioning or dehumidifying air, you can find out how much heat will be added or removed from the air.On the psych chart: Enthalpy lines run diagonally across the chart the same way the wet bulb lines do. They’re nearly parallel, and usually only one or the other is shown.Specific volumeThis is an easy one. It’s just the reciprocal of density. Instead of mass per unit volume, it’s volume per unit mass. But the mass used in psychrometrics is that of the dry air component.On the psych chart: Lines of constant specific volume run diagonally across the chart in the same direction as wet bulb temperature and enthalpy lines, but at a steeper slope.Humidity ratioThis is what’s usually shown on the vertical axis on the right side of the chart. It’s the ratio of the mass of water vapor to the mass of dry air, as shown in the equation below.W = mWV / mDAIt’s sometimes called mixing ratio and a few other names, but in North America, humidity ratio is the name most often used. With a little bit of math involving the ideal gas equation and the equation for barometric pressure given above, it’s not hard to derive an equation for humidity ratio based on the barometric and water vapor pressures:W = 0.62198 x pWV / (pbar – pWV)It is left to the reader to derive the form based on relative humidity. (Go on! It’ll be fun!)Now, let’s talk units. (We have this little weight/mass problem in those annoying imperial units, so think mass, not weight, when you see pounds here.) Humidity ratio can be given as pounds of water vapor per pound of dry air. In that case the humidity ratio scale would run from 0.000 to about 0.025.To make the units a bit friendlier, we can use this strange thing called a “grain” of water vapor. Turns out it takes 7,000 grains to make a pound, which makes the scale go from 0 to about 180.On the psych chart: Humidity ratio lines run horizontally across the chart, as do dew point temperature and vapor pressure. To avoid confusion, only one set of those lines is shown.A term to avoidGatley defines some basic terms at the beginning of the book and also includes four terms he classifies as “discouraged.” The one I hear the most is absolute humidity. I have to confess I’ve been guilty of spreading this term myself, but I’ve recently reformed my ways.Using the term “absolute humidity” isn’t as bad as saying “comprised of” or using the word “data” with a singular verb, but it’s ambiguous. If you look for definitions of it, you’ll find some that say it’s the same as humidity ratio. There are well known charts out there that do this, putting units of humidity ratio on the axis along with the term “absolute humidity.” According to Gatley, this is the standard definition in the field of physical chemistry. Much of the world, however, defines absolute humidity as the mass of water vapor per volume, which is not what’s plotted on the standard psych chart.It’s best to avoid ambiguity and use humidity ratio instead of absolute humidity.Putting them all togetherIf you’re still reading this article, you’re on the road to qualifying for Don Gatley’s Psychrometric Fools Society. You’re also on the road to understanding how all these things come together in that beautiful graph we call the psychrometric chart. Next time we’ll dive into that.Answer to dew point question: Changing the temperature only has no effect on dew point. Allison Bailes of Decatur, Georgia, is a speaker, writer, energy consultant, RESNET-certified trainer, and the author of the Energy Vanguard Blog. Check out his in-depth course, Mastering Building Science at Heatspring Learning Institute, and follow him on Twitter at @EnergyVanguard. Psychrometrics, you may recall, is the science that involves the properties of moist air and the processes in which the temperature or the water vapor content or both are changed. To understand how all that works, we need quantities and we need them to be well defined. Some are easy to understand (e.g., dry bulb temperature and barometric pressure); others are a bit more abstract (e.g., enthalpy). Here we’ll take a look at the main psychrometric quanitites, define them carefully, and tell which commonly used term you should avoid.The properties of moist air can be described by dozens of quantities. Don Gatley, in his book Understanding Psychrometrics, says there are more than 50, with one piece of psychrometric chart software allowing you to plot as many as 63. We’ll confine ourselves to the top nine in this article, but I’ll also tell you about a couple of terms it’s best to avoid even though they’re commonly used.In defining the nine psychrometric quantities below, I’ll give you the basic info about what they are, what might make them confusing, and which ones can be measured. The majority of the dozens of psychrometric quantities we could work with cannot be measured directly but rather must be calculated from other, measurable quantities.Another important thing to understand is that to determine a state point on the psychrometric chart, we need to know the values of three independent quantities:Barometric pressure (or altitude, from which we can get the barometric pressure).Dry bulb temperatureA quantity that tells us how much water vapor is in the air. It could be wet bulb temperature, dew point temperature, relative humidity, or any of a number of other quantities.The top nine quantitiesHere’s Gatley’s list of the top nine psychrometric quantities, sorted by whether we can get them by measurement or have to calculate them.

Exercise: A Holistic Exploration of What it Means to Move Your Body

first_imgAuthor: Christian Maino Vieytes, B.S. Nutritional Sciences, University of Maryland, College Park, M.S. Candidate, Division of Nutritional Sciences, University of Illinois at Urbana-ChampaignWhy exercise?The contemporary context of living has given way to a generation of individuals with sedentary and generally unhealthy lifestyles. Along with these changes, we have seen dramatic rises in chronic illness such as obesity, diabetes, cardiovascular disease, and cancer.1,2 It is not merely coincidence that these phenomena have coincided in their manifestation. Large epidemiological studies have demonstrated that at least some form of vigorous daily exercise is associated with decreasing risks of mortality compared to not performing any form at all.3 Disequilibrium in the work-life balance and industrialization of economies in Western societies have culminated with the sedentary posts that the majority of society’s members have been relegated to. Unfortunately, many fail to meet the threshold minimum for daily exercise.What if I don’t have time?One may find themselves repeating, “I wish I had time to exercise.” The truth is that obtaining adequate amounts of daily exercise may be easier than one believes. The traditional exercise archetypes that we envision give us the impression of exercise being a strenuous or difficult undertaking. However, it must be underscored that simply getting up from one’s desk and taking a 10-minute walk, a few times per day, may satisfy your daily requirement. The key to incorporating a new exercise regimen involves a gradual approach and setting short-term goals, whereby the level of exercise is augmented slowly.4,5 This may take the form of a 15-30 minute walk in the early phases and may eventually progress to a jog of the same duration. Many are drawn to the practice of yoga, as it unifies both a physical exercise routine with a mindfulness component that has been demonstrated to potentially alleviate symptoms of depression and anxiety.6The body’s potential for adaptation to exercise is remarkable. The earliest changes seen involve enhanced capability of red blood cells to carry oxygen throughout the body, enhanced ability of the body’s cells to utilize fat more efficiently as a fuel source, as well as changes to the structure and function of the muscles themselves.7–10 Exercise has also been shown to elevate levels of a key hormone-like molecule called brain-derived neurotrophic factor (BDNF), which has been associated with promoting brain health.11,12Ok, how do I get started?The public health recommendations for weekly exercise time are all but absolute. Different health authorities and organizations set their own standards. Generally speaking, the consensus amongst scientists is that we should strive to get 150 minutes of moderate intensity or 75 minutes of high-intensity exercise per week.13 This can be as easy as taking a brisk 30-minute walk five times throughout the week. Other common recommendations often touted by public health campaigns include reaching 10,000 steps per day or engaging in and maintaining a garden!14 The exercise regimen need not be highly structured—the importance lies in moving your body through whatever form that takes.What are other benefits of exercise?The benefits of exercise extend beyond that of just physical well-being into the realm of the psychological. Moving one’s body has also been demonstrated to help improve mood and abate the severity of depression in those who suffer from the condition.15 It has also revealed to be an effective remedy for diminishing symptoms of anxiety and for combatting insomnia.16,17 Many of the studies that examine the relationships between exercise and psychological function are novel, and further research in this arena will clarify these findings. Nonetheless, these early results do support a role for exercise in promoting psychological well-being.We have examined only a subset of benefits that can be accrued through a regular exercise program. Critically, physical movement forms a core component of what we understand to encompass overall wellness and well-being given the effects extended upon different domains of health. As highlighted,  these span from the physical to the psychological and neurological. These are the ingredients to longevity, but more importantly, for living a balanced and healthy life. It is critical to choose an activity that will be fun and provide joy at the same time that it imparts all of the benefits we have discussed. Playing a sport with friends is an ideal way of achieving your daily exercise requirement while at the same time building community. Simply moving our bodies more is what the goal should be.
