I was of this same mindset until a friend of 25 years died of it (To quote his wife "most horrible way of dying") and watching another friend in his mid 40's great shape, healthy.... can't walk 50 feet without sitting down to catch his breath. I know thats just 2 cases but IF you do get this, it has the potential to be real nasty.
I don't have kids but if I did I wouldn't let mine take a chance over a football game.
Our way of life has changed. I don't like it. But it has.
