Space Settlement FAQ's]

In regard to "a sleeper car on a circular track ...", is 1 g while
sleeping useful? Or is standing up with 1 g needed, where there are
mechanical stresses on the bones and hydraulic stressed on the circulatory
systems? We may well learn that humans are diverse and perhaps some group
that we have no way to suspect now will be able to handle low g better than
1 g. Like the Navaho's working "high-steel". My advise is to not start
construction until more is known!
My previous comments on oxygen were too sharp, and I apologize.
