Why not retire? (Score 1)

If this guy has enough money to splurge on going into space why is he still a real estate developer. If I had that much money I'd retire (I hope) and be giving a lot of it away to people who could make better use of it. I seems to me that no matter how much people have they are always working for more, perhaps aiming for a satisfactory amount of wealth or achievements that nobody seems to reach. After flying through space as a tourist I can't think of much more that you can strive towards, but I bet this guy doesn't retire even then.
