Also, VO recently got this question:
After I mentioned that vegans must rely on fortified foods or supplements for vitamin B12, this person cited that fact as evidence that nature intends for humans to consume animals or animal secretions. This person's point had me incapable of responding. What is your take on this comment?
Jack replied: "Nature doesn't "intend" anything - things just happen, humans evolve. As a vegan of 23 years, who takes B12 supplements, and is still alive at the ripe old age of 44, I would never want to trade my current state of health for the state of health of any 44-year old prehistoric meat-eater."
