In my own life, I decided to leave meat off my plate in medical school, but was a bit slow to realise that dairy products and eggs are not health foods either.

Not only are the studies themselves often lacking even face value, but they also drain badly needed funds away from patient care needs.

Dogs have a sense of smell much greater than ours and they're much faster than we are. We have fairly dull senses, fairly slow locomotion. In our Olympic trials, we celebrate speeds that would be an embarrassment to a bird or a dog or another animal.

It's much better to say, "If the herd is running, I'm running with those guys." And humans have herd mentality.
