In Malaysia, it's all the thing to boost a flagging libido with a dose of fresh rattlesnake blood. A wife will catch a rattlesnake for her husband, or he can go to a special parlor where he lies on the floor while an attendant stands above him and pierces a live, thrashing rattlesnake in the tail. The gentleman then grabs the tail and sucks on it for five minutes. One 63-year-old man reported, in a story in the S.F. Chronicle, "It's well worth it. I feel young again. It's better than any Western aphrodisiac I've tried."
