Being in space helps your skin

On the bright side, after about a month in space, big chunks of skin (calluses) fall off your feet, leaving them as soft as a baby’s. Could space travel be a mini fountain of youth? When researchers looked at astronaut Scott Kelly’s DNA, they found that the ends of his chromosomes got longer during his 340 days in space. That was surprising because they usually shorten as we age. “More research is needed, of course, but it certainly cracks open the question of whether spending time in space could reverse the aging process,” says Colorado State University’s Susan Bailey, PhD, who conducted the research. Whether that feat could be accomplished is definitely one of the most baffling mysteries about the universe.
