I don't know really why I'm posting this link, because it's rather disgusting. (I apologize). But I think pretty much every one dealing with SCI or similar just hates the embarrassment of bladder or bowel accidents. I certainly do. And so do little kids and elderly folks. But it's no biggie for marathon runners? I guess it's all a matter of perspective. If you think about it, anybody dealing with disability is an athlete by virtue of maximizing what we can accomplish physically.
