I was thinking about the Nutty Putty Cave incident and how one of the things that contributed to the urgent need for rescue was that the diver was upside down. He had hours.
Meanwhile, people have spend months, years in space. If we’re so sensitive to gravity, how can we deal so well when we remove it completely?

My understanding is that space does actually impact people negatively as well. The astronauts on the ISS have to work out at least two hours a day to minimize bone density loss, muscle atrophy, and cardio problems. The body was made to work with a little bit of resistance.
IIRC some of the work they do up there includes studies being done on the best ways to counteract these effects so that people don’t suffer as many long term problems if we were to send them out for years at a time for longer missions.
