Another unwanted side effect of spinning is the sopite syndrome. Physically, this is a very important result because any spherically symmetric mass distribution outside the position of the test mass m can be build up as a series of such shells. The other possible negative effect of G force is that during its implementation to the body, blood rushes toward the heart. When placing a human under high acceleration the brain, lungs, ribs (any bones), and women's breast (tissue fat) all affect the death of the human. The moisture returns to the disc overnight, but not 100%. For one thing, it tells muscles and bones how strong they must be.
