Friends, Many years ago—in a book about building space stations—I read that humans can thrive and maintain enough bone density and muscle to successfully reacclimatize to live at 20% Earth's Gravity.
I don't remember the name of the book and since we can't simulate 20% Gravity here on Earth, I'm curious how the figure was arrived at.
At any rate, picture a multi-tiered structure with artificial gravity ranging from 60% with levels at 50%, 40%, 30% & 20%. the main character spends time doing manual labor on each of the levels regularly.
However, his house has 60% Gravity—but his bedroom is set to 10% to maximize rest. He also has a weight room at 100% Gravity where he spends 2 or 3 hours lifting three time weekly AND he has a walking track where the gravity is 130% Earth's Gravity.
Should he show any bad effects—or benefits—from spending about two-thirds if his time in a low-gravity environment?
