Food, exercise, rest – these are all things that we need to survive and produce life. However, while all of these things are inherently good, in excess they can be harmful and even deadly. In America we have somehow learned how to take things that sustain us and make them part of our gluttony-fueled lives. For many people, food is a drug. It becomes something that controls them and causes urges that stronger than their willpower. Our ever-increasing visits to restaurants and calls for take-out also cause us to have “portion distortion”. Most restaurant chefs are dishing out portions that are two to four times bigger than the government's recommended serving sizes. We need food to live, but too much and it will kill us. The same can be said for exercise. There are many people who feel the need to exercise to an extreme level. I consider myself a runner and running is my staple exercise. However, I have always thought marathon runners were a bit on the insane side – I respect the discipline and determination that it takes, but let’s be honest – the Athenian dude that ran the 26-mile route to Athens to announce victory in the Persian war died of exhaustion. Furthermore, a Minneapolis Heart Institute study recently found that men who’d competed in marathons for 25 consecutive years showed 62% more arterial plaque than sedentary men. But, don’t think you can just lie around in bed either. A 2010 study in the journal Sleep, men who logged nine or more hours of sleep a night were 43% more likely to have heart disease than those who slept seven hours. So, there is obviously a need to keep everything in moderation.
