Are you taller lying down or standing up?

Yes, A persons length from head to toe is greater after lying for a long period of time. This is because the gravitational stress on our joints is not present when one is lying down flat. This is a fact that has been known for a very long time, and was proven recently on a discovery television show called "Mythbusters.". the answer is yes. you are taller laying down than you are standing up.
