The one thing I can think of is that our body is used or moving in the force
of Earth gravity and pumping fluids in that same force.  I would think that
our muscles and bones would weaken if we were out there for long.  Our
bodies are very clever and are constantly adapting to the changes.  If we
stayed too long our heart might just decide it did not need to pump very
much.  Our brain might be a little upset.
