Re: Extreme Kung Fu
I believe it's from a very obscure and esoteric sect of Taoism which has it's roots in tantric yoga - using sexual energy to attain enlightenment.
Some of the ideas aren't all that weird, (well, OK, maybe pulling a Boeing 747 with your doodads is a bit xtreme), but some of the exercises are rather interesting, particularly the ones which involve exercising the pelvic floor (women who've had kids know what I'm talking about). Apparently western science has recently discovered (or so I've read), that pelvic floor exercises in men over a certain age, has the potential to reduce prostate cancer. So maybe it's not that kooky after all?
