We know that for the last 300 or 400 years, the size of human bodies is growing. Now what happened is that we suddenly, in history, have the backward process.

Dictatorships can exist with free markets - not that China is really a free market - especially in poor countries where the regime insists that it's a choice between food and liberty, a false choice. But increasing affluence will inevitably result in political pressure.

I now have Croatian citizenship, but I only accepted it because Croatia allowed me to keep my Russian passport.

I would say that when you go to the very, very top, it's an ability to come up with new ideas, with something new, to make the difference.

Chess - it's a nonmainstream game. And the irony is that when you look at Hollywood, it kept using chess as the symbol of intelligence for its heroes, for its top characters, all the time.
