http://en.wikipedia.org/wiki/TorporHere's one from daffy dave and feeble eagle, when confronted with the quantity of food available on the ark for all those animals.........."Animals don't need three squares a day, and being at sea can make you sea sick, so you don't eat as much."
So the animals were "sea sick" and didn't eat much, problem solved!!!!!
Feeble eagle goes on to tell about being sea sick on a deep sea fishing trip, they went out 200 miles. Hope it was an overnighter, as it would take approximately 50 plus hour to motor 200 miles. Personally, I think he's full of shit!!!!!
Loony, you can go a month without eating. Of course your as*hole will turn inside out for a while, which may benefit you. Would give you a real view of the world. You get numb from the experience. Get some nutrition on occasion and you can function on a lower level for a long time. Man and animal were built for feast and famine.
You can bounce back from it with no real ill effect. In fact, it can rid you of bad things. Cleanse the system. Not so good for developing organisms like children, but adults are pretty much set.
