The Purpose of Physical Pain

Some people have said that pain is useful because it lets you know that you are alive. I reckon that may be true, but most of us dislike pain because it hurts. We do not want to hurt. Simple. There are a few people who like pain, and some people think that this is because the line between pleasure and pain is a bit fuzzy.

There are conditions where people do not feel pain, and they have to be exceptionally careful or even have someone watch them because they can be damaged and not know it.
