Question:  Is there a long term effect if you are floating in space for a long time?

Answer:  The one thing I can think of is that our bodyis used ot moving
in the force of earth gravity and pumping fluids in that same
force.  I would think that our muscles adn 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.
