It's a wonderfully moving sight to behold- people who refuse to be limited by their physical "limitations". I have taken yoga classes with extremely overweight people who could barely see their toes, much less touch them. I have run beside people with Cerebral Palsy and Parkinson's disease. (ahem, by "beside", I mean they ran right past me.) It may be the popular opinion that these physically "challenged" people have no business in the gym, in yoga class, or running a road race. This kind of thing should be left to the "real" athletes, right?
In my opinion, these ARE the real athletes. Despite all the reasons why not, they think to themselves, "yeah, why the heck not?" And, then they go for it. It takes little courage to think of yourself as an athlete when you look in the mirror and see a muscular, lean mean athletic machine. It takes much more to look in the mirror and see reminders of your weaknesses staring back at you and still know you ARE strong.
