> (Conclusion: walking on the moon is healthy?)
NASA vetted the Apollo astronauts for those who did not have medical problems, so it would be more accurate to say they walked on the moon because they were healthy.

I mean, you don't have any data (or evidence) on that one way or the other; do you?
ADDED. Oops: the comment 3 levels above gives data. I regret wading into this thread.
If this conscientious attitude translates to health, that would mean "going to all your yearly checkups" and "don't pooh-pooh any small symptoms because you are macho and true men don't care". I know far too many men who died of something treatable by ignoring it until it was too late. (Women, at least around me, tend to be a lot more careful about themselves.)
I am now reading Michael Collins' biography - a talented writer btw. - and basically, they were used to very intrusive and systematic health checkups. I can see them developing a good habit out of this.
During the Apollo program any sign of weakness or vulnerability would be a reason to ground an astronaut, very likely permanently. So they regularly concealed absolutely anything and everything that wasn't directly expected or related to the mission. This included various forms of sickness or injuries, space adaption sickness, psychological issues, and more. Alan Shepard even managed to conceal symptoms of what would later turn out to be Meniere's disease.
Aldrin was friggin touring around Antarctica in his 80s where he ended having to get on an emergency evac! It's not exactly a caution first attitude to life. In general the secret to longevity is healthy living, good diet, and a positive outlook on life. Even the Ancient Greeks had countless people living into their 80s and beyond.
