If we couldn't feel pain it would have some good and bad side affects. If we couldn't feel pain the good part would be that we wouldn't hurt if we got small injury like paper cuts, bumping into counters, and so on. But that brings me to the bad side of not being able to feel pain, if we couldn't feel pain and got really hurt like a broken bone, shot, or a fatal head injury it could be really bad for us because we might not be able to know until it was to late. and that's what might happen if we couldn't feel pain.
