I see what keeps people young: work!

If I had to predict, the way things are going, I'd say the chances are about 50-50 that humanity will be extinct or nearly extinct within 50 years. Weapons of mass destruction, disease, I mean this global warming is scaring the living daylights out of me.

I don't watch entertainment. I haven't watched in years. I want to see serious news.

I fantasize about everything; being a fireman, an Indian chief, climbing mountains. Anything is possible.

I lost 80 percent of my wealth and then gave away over half of the rest. So I'm a man of modest means now. But if you budget carefully and watch your expenditures, you can get by on a couple billion dollars.

What the Bible says is really true-it's better to give than to receive.

I regret that I wasn't more successful with my marriages, but it is what it is.
