We humans are very used to gravity. We live with it every day! What gets hard when it goes away?

This might be a hard question to answer for most of us, given that a very small percentage of us are astronauts, but it’s a interesting question. Certainly some things get easy (like holding another person upside down with a single finger) but there’s bad with the good.

What’s the hardest thing for humans to get done without gravity helping us along?
