If people had three hands instead of two, would we say we wished we had a fourth hand?
I was wondering about this as I carried nine plastic bags of groceries in my two hands from the car to my front door. I may have strained every tendon and ligament in my fingers, but by golly, I got everything in one trip! Of course, I had to put down the bags to unlock the front door, which made me wish I had three hands. But if I had three hands, wouldn't I just carry even more stuff in those hands? Then I would wish I had a fourth hand. So I guess my thinking is that if we had three hands, we still wouldn't be satisfied. We'd always want more. Thoughts?
