“...a spacecraft is passing and some human is up there hefting a lift-bar with her legs, willing her muscles not to give in to the seduction of weightlessness, nor her bones to birdness. Else that poor spacefarer will be in all kinds of trouble when she lands back on earth where legs, once more, are very much a thing. Without that hefting and sweating and pressing she would survive the blazing heat and tumble of her re-entry only to be pulled from her capsule and fold like a paper crane.”
