It’s all endorphins. Use any muscle a lot, and you’ll raise your endorphin level, thereby feeling better due to the activation of endorphin (opiate) receptors. Be aware though, that this is not a proven long-term treatment for true endogenous depression. Reactive depression, brought on by stressful situations, may be improved by endorphin induction.
Nurse: Doctor, why do you have a thermometer behind your ear?
Me: Dammit, some asshole’s got my pen!
mouthbreather actually has this book. I haven’t seen it in a while, but when he first got it, it seemed to be very good bathroom reading (for him, anyway). I’ve flipped through it a bit, but reading foreign concepts in very elborate, yet broken “engrish” gives me a headache.
I can’t say that constricting my anus will cure my depressiona but the laugh I got off of those reviews sure brightened my day. That and I’ll be humming “If you’re happy and you know it…” all night.
Anything that’s terrifying enough to make me clench up my anus (ie drop bears, discussion of “female problems”, etc.) is going to command a lot more of my immediate attention than some silly old bout of chronic depression. So I can understand the operative mechanism.
