Being in London has really taught me how important history is. Just having information of the past. It helps you predict the future, which is all we really have as, you know, humans.

The stock market crash in October 1929 didn't destroy a particularly large amount of wealth or make people highly pessimistic. Rather, it made companies and consumers very unsure about future income, and so led them to stop spending as they waited for more information.

Performance art is going to be the future. Plays on Broadway are so restricted. But performance art is like haikus, just one line thing. And it's more casual but more interesting.

In the future, we will probably see cyber operations that change or manipulate electronic information to compromise its integrity instead of simply deleting the access to it.

People thought I was funny, so I kind of took entertaining for granted... it was inevitable that I'd start giving little performances.

I particularly like Twitter, because it's short and can be very funny and informative. It's a little bit like having your own radio program.

I had several turtles before they were in. People seemed to think they were funny. Now everyone is wearing them practically every place. I think that's real fine, but I don't agree they should go to a formal affair. Turtlenecks with dinner jackets seem ridiculous to me.

I look at old performance videos now, and it's really funny - I thought I was such a gangster!

Censorship no longer works by hiding information from you; censorship works by flooding you with immense amounts of misinformation, of irrelevant information, of funny cat videos, until you're just unable to focus.

If Reagan had intelligence information that showed that the upheaval in Egypt is actually Democratic in spirit, then he would have, I believe, turned his back on Mubarak, even though there's a long friendship between the United States and Egypt.

My last public performance for money was in 1967. For free, it was 1972, with the exception of two little one-shot, one-song things. But that's just for friends, out of friendship for the people involved, and also because it was fun.

A youth, when at home, should be filial and, abroad, respectful to his elders. He should be earnest and truthful. He should overflow in love to all and cultivate the friendship of the good. When he has time and opportunity, after the performance of these things, he should employ them in polite studies.

To avoid being mistaken for a sellout, I chose my friends carefully. The more politically active black students. The foreign students. The Chicanos. The Marxist professors and structural feminists and punk-rock performance poets.

The road to freedom lies not through mysteries or occult performances, but through the intelligent use of natural forces and laws.

Forgiveness, in some cases, is a flipping miracle in the sense that you're fighting, and suddenly something happens. It's a kind of grace. Whether you believe in God or not, something happens, and it's transformative.

I can't say this enough - the food that you put into your bodies can actually help you get better grades. And it can also affect your performance in sports and other activities too. You see, when you give your body the best possible fuel, you have more energy, you're stronger, you think more quickly.

Because of media hype and woefully inadequate information, too many people nowadays are deathly afraid of their food, and what does fear of food do to the digestive system? I am sure that an unhappy or suspicious stomach, constricted and uneasy with worry, cannot digest properly.

There is no doubt that some plant food, such as oatmeal, is more economical than meat, and superior to it in regard to both mechanical and mental performance. Such food, moreover, taxes our digestive organs decidedly less, and, in making us more contented and sociable, produces an amount of good difficult to estimate.

The food we eat goes beyond its macronutrients of carbohydrates, fat and protein. It's information. It interacts with and instructs our genome with every mouthful, changing genetic expression.

Organic food is the best for you, and I'm eating the best, a lot of fresh vegetables. I also keep myself hydrated. It's all made a big difference to my performance in the gym.

While weight loss is important, what's more important is the quality of food you put in your body - food is information that quickly changes your metabolism and genes.

My unique contribution to the fitness industry is bringing fitness into the home through cable, VHS, DVD and now digital formats.

I'm not ashamed to admit that for many years, most of my fitness information came from a VHS series by MTV called ''The Grind Workout.''

I think fitness and performance levels are the right indicators to determine if it's the time to leave the scene.
