Manny Pacquiao?

That's the point. To reduce the amount of pain you feel

 

i think he was joking but he had a crazy murderous serious glint in his eye

 

i can't believe you don't think the body gets tougher??? you break it down and the body builds it back stronger .pretty simple

 

Neural pathways don't work like muscles. You destroy them and they are basically gone forever.

 

Exactly, infact Roach doesn't really like it but its something manny believes in so he lets him do it.

 

i'm talking about the bones and muscles.pain tolerance goes up to. like the people that break concrete or wood with there hands .

 

Unless pain tolerance increases because nerves have been destroyed.
