Well, I imagine that it may be good training but I'm still going to pass. I've done the "without food" thing and still do on a nearly daily basis, only eating when I get really hungry, but I do have a limit and I would be feeling awful after even two days.

Shoot, I'll eat a McDonalds Cheeseburger after a couple days of nothing. I'd probably start eating bugs and worms after three days, shoe leather by four, any longer than that and I'd be inviting the "others" over for a "Donner Party".

Maybe that's why I always carry too much food when I head out
