Answer: When we are in equilibrium with our surroundings, we don’t feel our surroundings.

We adapt automatically to it, so if you then go into space, you are effectively weightless.

When you come back down to earth, you will need to be supported/carried upon arrival because the brain will need to re-adapt to the change.
