If you're a cartoon character or most TV characters, sure, you'll fight, because the punches are juicy-sounding and they don't leave marks. But in real life, if somebody punches you in the eye, it doesn't make any noise and your eye is swollen for, like, six months. It's a nightmare to get punched in the eye.

Some things I think are very conservative, or very liberal. I think when someone falls into one category for everything, I'm very suspicious. It doesn't make sense to me that you'd have the same solution to every issue.

I like pressure. Pressure doesn't make me crack. It's enabling. I eat pressure, and there might be times when I get a bad feeling in my gut that this might be too much, but you feel pressure when you're not doing something, you know?

When I start getting embroiled in heated debates and feeling stressed, I just turn everything off and disconnect from the world. I simply tell my colleagues and friends that I am not well and need to cancel all meetings for a day or more. I take it easy - go for a long hike, take a vacation somewhere, or just stay at home and read.

Supplying fuel for a Mars expedition from the lunar surface is often suggested, but it's hard to make it pay off - Moon bases are expensive, and just buying more rockets to launch fuel from Earth is relatively cheap.
