We all know the pictures of the astronauts on the ISS floating around. We also suspect that a lack of gravity is bad for the body as the muscles go weak and such.
Why don’t spaceships just rotate to cause the effect of artificial gravity through centrifugal forces?


LOL of course it is doable to create rotation. But is it no good if living there is still unbearable.
I recommend you do some sea traveling, just a few months on a cargo ship on several oceans.
