Pain/No Pain

I read an interesting article today, about a little girl who cannot feel pain. It's a problem with her nerves, or something, I don't recall the details but it was just fascinating.
For a moment I wished we all had that ability, but then I took it back.
Because feeling pain can be a good thing.
It reminds us that we are alive.
It alerts us to physical danger.
For some people, it can serve as a release.
Not feeling emotional pain, now there's a health problem I think we can all get behind.
