Thanks CraigD that actually brings to light more fodder

The other reason I was asking was that current space vehicles are small. The bigger they get the more you'd need to move around actively. Where you could argue that regardless of Mir or ISS or a space shuttle being in space or on the ground, a full gee, the passengers just can't move around that much and might not be able to move around enough to be as healthy as a person free to walk around.

So in a much bigger microgravity environment, inhabitants would still need to move around. The more they do, and the more physically active they are in doing so (think of it like swimming or flying, but from point to point. They'd need flee jump from place to place and still need a very acute 3D spacial sense to move around a 3D environment. Granted simply staying upright gives us more exercise than would be needed to float around in microgravity, jumping around and more importantly landing and redirecting, considering inertia could provide as much exercise as a gymnastics tumbling routine would.. but daily. In addition to things like dedicate bone conditioning, starting from a very young age, even though they might not be able to adapt to gravity being a constant thing they need to fight against (getting gravity sick etc). I think It could be managed fo kids born in microgravity to adapt later on to life on the ground.
