Controlling pain is a *major* evolutionary disadvantage. Pain evolved
as an evolutionary advantage; removing it is a disadvantage. People
with off-switches for pain would not tend to survive to adulthood.
Pearce lists among his bookmarks a fellow who experiences no pain. He
once had trouble closing a door, only to notice that his hand was stuck
in it. It's amazing that poor guy's still alive, pleasant as his life
may be.
So in answer, your statement is correct but *you* are completely wrong.
