#6 Some daily facts about space flight!-
Astronauts who spend extended lengths of time in microgravity develop many different conditions, some of which cause the body to age more rapidly than it would on Earth. They have to undergo weeks of reconditioning when they return.
A few of them are: redistribution of body fluids, swelling of the brain, change in heart shape, bone density loss, muscle atrophy, lower blood pressure, constricting of the blood vessels, visual acuity, and more...
The soles of the feet thin out significantly from lack of use, and it becomes painful to walk upon return to gravity. Also... lack of gravitational compression along with fluid build up causes the spine to stretch, making the astronauts temporarily taller.

#2 Someone finally got it right. The myth is that they continue to grow. What really happens is the skin loses elasticity with age and begins to sag. Well done, Izi.
