Children dislike green leafy vegetables. Adults like them. :)
You know, if he walks across America, he'd lose a lot of weight. When I was in Marathon Training, (maybe 9 hours of working out/running a week) I lost a solid 20lbs. Just walking and controlling his food intake would make a huge difference.
That'd disappoint me, to walk all the way from CA to Ohio and still weigh 300lbs?
There's an obvious flaw in his plan if he does arrrive in NY and is still a porker. Tell me that wouldn't reinforce a futility?
My guess is he's stopping because he doesn't want to arrive in NY in that condition. If he does, what's the point? he'll be quite depressed and wonder even more what life is all about.
