I'm not a biologist, but I definitely suggest checking out the National Geographic documentary. Maybe someone else on here has the title.
I think you are talking about Fight Science. To the poster, yes you can strengthen your bones so they hit harder, killing the nerve endings makes it hurt less. I would highly suggest to learn these techniques for bone strengthening from an instructor in real life...can be pretty dangerous if you don't do it correctly.
