Seriously, if you think about it the thumb allows us to grasp things. The muscles never evolved for fine motor dexterity.
I never thought about thumbs in this way. Makes me think about all that gaming I used to do when I played on my Nintendo and Super Nintendo. And what about text messaging? I don’t do that heavily, but I’m sure there’s some people that use their cell phones in conjunction with AOL Instant Messenger. Don’t mess up your hands.
We’ve already messed up our bodies by wearing shoes and doing all sorts of strange things with them.
