Every day when I look in the mirror, and I don't have this problem.

Then again, by the time I had a touch typing course at age ten using an old typewriter, I already had taken piano lessons for a couple of years. My music teacher was very strict on proper hand positioning, saying that future me would hate him if I didn't learn that right. I stopped taking piano lessons soon after, but I imagine that the skills involved with properly playing the piano transfer quite well to typing.
