Hi its crazyeli100 and yesterday I was reading a magazine focused on astronauts and on one part it mentioned that if the astronaut doesn't exercise in space their bones can get weaker because the gravity is lower in space. I was thinking if you go on a planet or space station with gravity weaker than Earth's and you spend more than 5 minutes there, when you return to Earth you get weakness for 5 minutes because of your weak bones. (Just don't show weakness particles) A way to avoid getting weaker is to walk 200 blocks every so often on the planet which is exercise but, if your on extremely low gravity, (Spacestations, moon etc.) you can use an exercise machine provided by the mod. Thanks for reading my suggestion!
