Are you over 50, retired and bored? AARP has a suggestion: Mars
Today, they suggested Mars. It appears the ideal couple for this trip is over 50 and has been married long enough to get the kinks out. And since the round trip is only 501 days, if done in 2017, it is less time than you would spend with the Peace Corps. There are probably a few risks, but the Geezer, at 73, is already facing a few risks. Old age is the ideal time for new risks, a lot like your late teens and early 20’s.
There are a lot of plusses. Once you went through Mars “training” you would be in great shape. Your grandkids would really think you were “cool.” All social security could be banked/invested. It beats assisted living. You would have a lifetime of stories and could not only hit all the talk shows, but could “eat” off of your experience for the rest of your life. Any dementia, could be explained by the trip. You might run into a few aliens. And, of course, after the initial phases, it could solve the problem of what to do with old people; send them to Mars.
I can’t see a downside; and, at 73, that’s saying a lot. I expect a call from the Mar’s Mission at any moment.
