Question: I'm not a medical expert, but surely the level of bone loss shown in the movie would make it impossible for any of the humans to support their own weight?

Once More, With Feeling - S6-E7
Trivia: Alyson Hannigan and Michelle Trachtenberg don't have many singing lines during the episode "Once More With Feeling". This is because Alyson threaten to come down with laryngitis should she get to many lines and Michelle actually did come down with it.
Chosen answer: The level of medicinal care allowed a string of captains to live well into their 130s. Preventing or reversing bone loss seems like a trivial task compared to that.
