I think Kelly's right there. I didn't really consider losing my sense of touch because you never hear about it happening, but I think this is the most likely to be deadly. Don't people with leprosy lose sensation, and end up disfigured because of it? And wasn't there and Indian child who felt no pain, and died jumping off a house because he knew it wouldn't hurt, and wanted to show off?I bet loss of Touch would be the worst. It would be dangerous. You could accidentally hurt yourself very seriously and not even notice.
