29. How long can a person stay in space before feeling the negative effects of lack of gravity? (A K2S Question)

The effects of zero-gravity begin as soon as a person gets into space. Some go away, once the body gets used to zero-gravity, others continue for as long as the person is in space. There are also effects that occur when a person returns from space and has to get used to being back on Earth.
