Two Surprising Facts About Pain and Touch

You probably didn't know this. Your brain can't feel pain, even during brain

surgery. The brain itself has no pain receptors. Pain comes from nerve endings in

the skin and skull, but not from brain tissue. That's why doctors can operate on the

brain while patients are awake once the scalp is numbed. Here's another fact you probably didn't

know. You've never actually touched anything in your life. When you touch an

object, your atoms never meet its atoms. They repel each other through electromagnetic

forces, and your brain interprets that resistance as touch. So what you feel

isn't contact, it's energy.
