It suddenly occurred to how profound it is that humans are in living and working in space. It means out brains, our heart, our nervous system, our stomachs, our bowels, blood vessels, blood, haemoglobin, everything essentially (well, except maybe our bones), is able to tolerate microgravity.

I started thinking about this as I considered the orb-weaving spiders on the space station. They too, with some time and practice, acclimate to zero-G.

This means that evolution (or God) did not design us to die when off a planet, when away from a gravity well.
