It's hard for me to understand how a person could have a sense of touch but not feel pain. It seems like touch is just a continuum where pain is where it crosses over into being unpleasant. I've always been similarly confused about how painkillers work. Pain must somehow be an actually different thing than regular touch, but I don't get how this can be.
Sorry about the snarky response, but when a comment like this is at the top, I can't believe so many people have voted up what is basically F~cking Magnets, How Do They Work?
Calm down, my comment was at 1 (now 0) because newly-posted comments are slightly favored for a little while before falling down the page to be in pure score order.
