Calumt (sp?) who at age 120 has never worked a day in her life (she was into moderate biking). I grew up across the street from a guy who never worked either, & I believe he lived to around 104. (He didn't marry until 80, but I'll avoid the temptation of speculating as to whether an earlier marriage might have shortened his life :^) ) The Romans used to work people to death as a rather creative method of punishment. Somehow many in the West have gotten into a guilt trip over whether they are exercising enough, but I would look at it the same way Bohdi looks at protein: ask people how they get rid of the wastes exercise engenders. I'll repeat that in one or two postings to the CR list in Oct. or Sept. somebody listed several rodent studies which should remove any doubt on the negatives from exercise. The CR list is archived at: http://darkwing.uoregon.edu/~freinkel/crs/index.htm If anybody get ambitious enough to go look there, could you please send me (or this list) a copy of the relevant post(s) as I wish I had saved it, but am too intent on practicing active lethargy at the moment to go look there myself. I have no doubt that exercise when eating raw is probably a lot less harmful than when eating cooked, but the principle would still hold regardless of diet. Exercise is precisely analogous to mileage on a car: the more fuel you have run through the engine, the less life is left in it. --Doug Schwartz [log in to unmask]
