If a dog happens to catch a rabbit or another animal, it can very easily remove the hide. If a cat catches a squirrel, they have no trouble with that. But if a person does that, they will work all day and all night to get the skin off of an animal, because they don't have long canine teeth anymore.

The Stone Age gave us arrow heads and eventually knives, and that allowed us to kill animals in ways you couldn't before, and once you had them you were able to remove the skin and bones.

I am always struck by how difficult it is for people to see how much cruelty they are bringing not only upon animals but upon themselves and their loved ones and other people, how much we are screwing up the planet, how much we are hurting our own health, how hard it is to change all that, how eager people are to make a buck at everybody else's expense - all those things are discouraging.

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.

I thought - being a musician doesn't help your medical credibility really. Although I started to rethink that when I learned that Albert Einstein was quite a violinist and in fact would perform a lot with symphonies. So if it's good enough for Albert, it's good enough for me.

People do lose weight on an Atkins diet. The reason they lose weight is because of calorie reduction. If a person's caloric intake has not fallen, if they are really shoveling in the steak, they don't lose weight.

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.
