Sorry to be pedantic, but.....

Standing on the Earth isn't stable, as evidenced by the fact that both
bipedal and quadrupedal living creatures don't remain standing after
they die (and their proprioception -- brain -- muscles feedback loops
shut down): they fall to the ground.

[I think further discussion of how living creatures stand is probably
better off in some other newsgroup. I've set followups accordingly.]
