Going to space is definitely one of the coolest things a human could ever do but damn if it doesn’t do a doozy to your body. If you were able to spend time in space, your bones would become brittle, your leg and back muscles would wither away, the back of your eyeballs might flatten, and your heart could lose mass and become more spherical. None of that is good.
