Conversely, if you spend 8 hours a day in zero-G (powersat
construction, space sports, etc.), but the rest in full-G, is that
healthy?

This is true. AFAIK, we have zilcho data on humans (or much of
anything else) in low-but-not-zero-G.

I know that I've mentioned this before, but

"Nope."
- almost everybody whose looked at this in any kind of depth
