did you hear about this guy, who's walking across the united states from california to new york in order to lose some of his 400 pounds (he's down to 350 now)? he's got a fascinating, sad story. he has two kids and is afraid he'll die before he turns 50 if he doesn't lose a lot of weight. also, he is a former marine who gained the weight after accidentally killing two pedestrians with his car years ago.
