Damn. I wonder how well the hands work.
Speaking of hands... XD
I'm guessing not very well. After all, a hand is MUCH more complicated than a leg and foot. Think of all the complex, intricate movements your fingers make to hold a pen and write, or type something on a keyboard. Your foot basically moves up and down on the end of your leg. Comparatively, it's a lot more simple.
What really interests me for hands, though, is that they actually have something called hand transplants. I was watching CBC the other day, and they were talking about hand transplants. They showed this woman who lost both her hands and had transplants grafted on. At first, her fingers were all gnarled and she couldn't move them much, but they gradually loosened up, and what's more, she actually started
feeling sensations in her new hands. That's something you can't get back from 3D-printed prosthetics, as impressive as the new technological application is.
