You can't appreciate the term runner's high until you experience it yourself, and once you do, you'll be addicted for life because there is truly no other feeling like it in the world. If you are like many others, you probably see a runner and think they were just born to be fit or you get this overwhelming desire to hit the pavement yourself but get discouraged within the first couple of days. The truth is, anyone can be a runner regardless of weight, age, etc. Oh, and if you think you can't run because you have asthma, you would be surprised at how many runners throw away their inhalers once their lungs get stronger. If you have tried and failed to become a runner, you probably went at it the wrong way.
