My wife is very patient. On our honeymoon in 1992, we got a motor home and drove from L.A. to Idaho and then down the coast. I was running a lot, then so she would drop me off, drive six miles, park and wait for me.

There was a combination of not wanting to look a gift horse in the mouth, but also really not wanting to be stuck in Lord of the Rings for the rest of my life, and being desperate to kind of make sure that I could do something else with my life.

I personally think going to Mars, if it takes two years or two and a half years, that's doable. Certainly, the first people who go there, that's going to be a big motivator, being first getting to Mars.
