Very interesting read for everyone; whether they "believe" in acupuncture or not. Every time you hit your "funny" bone, now you are actually hitting an acupuncture point that's been known about for >1000 years.
But remember, this still doesn't mean that everyone can learn "pressure point self defense" and be labeled "deadly." ;)
