When it comes to physical pain, it’s purpose is hardly in question: It focuses us to where our immediate attention and action is required.
We accidentally rest our hand on a hot stove top burner and, without our sense of pain, our hand, if it weren’t for our sense of smell, would become cooked well enough to serve up at the next meal.
We could laugh at this, but sadly and horrifically there are some who do not experience the sense of physical pain due to a rare condition known as congenital analgesia.
