For one, I don't eat very much red meat, just chicken, turkey and fish mainly, but its still meat. And when I see a whole skint chicken or turkey, or fish, I do get hungry.
Also, your post says that Humans have flat back molars and no sharp front teeth. You are wrong about this. We have canines in the front and I don't know about you, but when I run my tongue across my back teeth, they feel pretty sharp. Not really flat by any means. And our ancestors as far back as they can trace....to "caveman" days...shows evidence that some tribes were hunter/gatherers and did in fact eat meat. So this is not something new. Humans have pretty much eaten meat since we were first documented into existance.
And as far as the vegan diet being unhealthy goes, it is not as bad as most meat eaters think. There is a small difference between soy protein and meat protein. Lean meats, like poultry, provide the body with important nutrients, including high-quality protein, iron, zinc, and B vitamins.
And as far as personal experience goes, I find that after a good work out and weight lifting, nothing helps build muscle faster and healthier than a nice serving of fish or turkey. Just my opinion.






What else is required for survival, but
porridge and whiskey? Hmmm? Well, maybe chocolate, and tea, and avocados, and Port Salut....but not much!
