Does this foreshadow a new space age of health spa tourism?
When astronaut Scott Kelly returned to earth a few days ago after being in space for 340 days, he could brag about a few other things than just being the person who has achieved the longest space flight for an American. Kelly returned to Earth taller and younger than he would have been if he’d never left. As CNN reports, Kelly came back to Earth two inches taller than he was when he left. His increased height isn’t due to bone growth, however. Being up in space where there is no gravity exerting force on the human body means that a person’s spine can stretch out by as much as three inches.
