For my next trip a crude oil bath

From the New York Times:

The petroleum spas of Naftalan in central Azerbaijan, one of the little-known but once popular vacation spots of the Soviet Union, are making an unlikely return in a country so awash in oil these days that people are swimming in it.

Here in Naftalan, visitors can bathe once a day in the local crude. They and doctors here say it relieves joint pain, cures psoriasis, calms nerves and beautifies skin — never mind that Western experts say it may cause cancer.
