People With This Condition Can't Feel Pain
Only about 20 cases of congenital insensitivity to pain have been recorded. Those affected by the condition have a genetic mutation that prevents the formation of specialized channels in their nerve cells, which would normally transmit pain signals to the brain. The condition makes life abnormally dangerous, as people with CIP often don't realize when they have been wounded.
