American Angel:
I have to say that it's not a good idea. I actually did the opposite, punching to cutting and scratching, but mix it up at times and I have to say that it's very unhealthy to put one's brain in jeopardy. It could cause brain damage, concussion, and not to mention other terrible things.

Please take care and consider finding something else to get release.
Stay safe,
Kimberly.
