It's not a joke. And Einstein was a very deceptive man. Half his theories weren't even his. Remember Microsoft and IBM OS? His beliefs as far as humanity is concerned come from a humanist/naturalist background. He also was very deeply involved with Mystery Babylon. Basically he was a eugenicist.
Why, if were not supposed to eat meat, does our body more readily accept complete long chain amino acids found in meat...as opposed to the shorter incomplete chain amino acids found in plants.
We need both, regardless. We need more plant matter than meat matter as well, which a lot of people these days fail to realize.
But please don't pawn cancer off on MEAT. Meat can act as an accelerant in someone who already has certain types of cancer. But meat, in itself, doesn't cause cancer.
As far as out performing, that may be a farce. When I was in the Marines, they would allow, with special orders, for vegetarian dining at meal time. All I have to say is...by the time the 13 weeks training was up, there were no more meatless eaters left. And believe me...we were pushed infinitely harder than most marathon runners.
Anyways, I hate arguing...I just never have liked it. So I probably will not reply to this again as such. But at least you didn't get bent out of shape like some people do, I appreciate that. Thank ya!
