What if clouds and lakes switched spots and every time you looked up you’d see waves being pulled by the moon and we’d wade through the clouds on a hot day. What if birds grew grass and the ground grew feathers. What if flowers were as tall as trees and trees as small as flowers.
What if you have hair instead of flesh and flesh instead of hair?
We’d have fun, but dehydrate and die pretty quickly if we didn’t come up with a good way of getting drinking water (shouldn’t be too hard; we can condense the clouds or stick pipes into the skylakes. I’m more concerned about the wildlife in areas dependent on rainfall).
Birds would lose the ability to fly. The Manx Shearwater would be screwed, but the penguin wouldn’t care much. The ground would be much cuddlier, but we’d have trouble feeding our livestock.
I’m not sure, but I’m worried about the flowers on the trees…
Taking the broadest interpretation of “flesh”, you’re dead, because the only living matter on you is in your bones and where your hair used to be. The heart has become hair, and cannot pump blood, so even that probably dies.
