I know otherwise. I have a lifetime of experience—lifetimes of experience, counting the experiences of other people—to know that pain is often just noise.

Pain is ancient. It predates rationality by millions of years, perhaps billions. The dumbest animal experiences pain. It's not a finely tuned system with documented diagnositic codes.
