Some questions about pain tolerance?

Question

Do genetics decide pain tolerance? Or is it a mental/physological thing? Is there any way to increase pain tolerance besides hurting yourself?

Answer 1

its a combination, also if you were raised hurting yourself alot, you will be less sensitive, my sister has high functioning autism and she walks into doors and falls hard and stuff like that and doesnt feel it, so in that case its genetic, and monks who can walk over coal and stuff, thats all mental. You can tell your body you are not in pain or danger and eventually [if you are very in tune] you can stop your nerve receptors from sending signals to your brain. They also do similar teqniques with  high class military soldiers so if they get shot or w/e they can continue their mission.
