Perhaps there needs to be more studies done on the effect of gravity and human health? Conversely, are there other things in our air (pollutants) that are in fact causing slower aging when on Earth?

I like the comment from petero:

Perhaps the effect is due to lack of grounding.

This is interesting. You feel gravity less when you are in fluids. Does this mean all babies feel gravity differently because we all experience different amounts of fluid in the womb (not to mention the variations in baby sizes)? The impact is probably miniscule but I wonder if it has any effect on development of babies in the womb.

Certain bacteria in bodies die in space?

So the dawn of the 20th century radium spas are going to make a come back? https://en.wikipedia.org/wiki/History_of_radiation_therapy#J...

If they absorbed sufficient radiation to kill that much bacteria they would be dead a week later. If you get a dose high enough to give you "radiation high" you are a goner.

Is there a citation for the following claim? I've never heard of such a thing:

"But then more results started coming back. Not only do astronauts come back with weak muscles and frail bones… But they also suffer from skin thinning, atherosclerosis (stiffer arteries), resistance to insulin and they suffer from loss of vision due to cataracts many years earlier than expected given their chronological age. These symptoms look a lot like skin aging, cardiovascular aging, age-related diabetes and so forth. In fact, it is pretty accurate to say that astronauts age at an accelerated rate."

That's a nice theory, but I'm going to call [citation needed] anyway. Can you cite any explanations of how weightlessness would cause something like cataracts or insulin resistance, or even of whether there's a statistically significant correlation focusing on the single variable of weightlessness vs. others that might be involved?
