Since I first went to India twenty some years ago, there's been a palpable change. There's now pizza everywhere, meat is much more popular than it's ever been. Vegetarianism is "that quaint thing our parents did."

I don't approve of the use of animals for any purpose that involves touching them - caging them.

While it's certainly true that many people think that dairy doesn't have a cost to the animal, it's because they never went to a dairy farm.

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

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.

The important thing is that while heroin and cocaine and tobacco and every drug and junk food cause dopamine release, there are healthier ways that you can put this into your life. And the three big ones are intimacy ... physical activity ... and the third thing is music.

I think herd mentality is a good thing overall. Because if every sheep had to figure out the velocity of the wolf and their personal risk, that would take forever.
