My biggest love is space. I completed 800 hours' space training in Moscow and I became the world's oldest man to go to the North Magnetic Pole. At 67, I also became the oldest man to reach 28,400ft on Everest without oxygen.
You know, I've always tried to look at things as just what the part was. I never tried to worry about whether it was the lead or not the lead, because I think you can really mess your mind up when you're too caught up in those things.
