LOL! Well watch that too, it's a fascinating documentary.

lol I was confused with the porn video too.
Dude, that looks really cool. I'll see if my wife will do that tonight. Her mom does gua sha or gao yaw which means in Vietnamese to "scratch wind". They use eagle brand medicated oil and a coin to scrape the back. I'm sick right now so I want to get this done anyway, but I might also do it for all the kinks in my neck and back. Chinese people do it with a blunt soup spoon. I wrote it off as an old Asian wive's tail but any time I have it done I swear it helps.
Thanks for the awesome vid. Really feeling like shit right now so I can't wait till the wifey gets home so I can get her to do my back like this lol
