Bodies are weird. There are many things about the human form that seem completely capricious and arbitrary.
If we were an alien species on a different planet, we might have a completely different type of body. I suspect that on a distant planet somewhere there is an alien contemplating its own body.
And I suspect it might be having exactly the same thought that I am having. It’s nice to think that we have something in common.
I wonder if other inhabitants of our planet have similar contemplations? Ever watch a cat observe its own tail? What is that cat thinking?
