6. Head-Drilling

There’s nothing like boring a hole in someone’s head to improve their wellbeing. Cave paintings suggest that trepanning can be traced as far back as the Neolithic period and was used as a cure for migraines, seizures, and other mental disorders. The practice of drilling, or scraping, a hole in the human skull continued throughout the Middle Ages; if a person behaved abnormally, trepanning was a way to let evil spirits out of the body. Boring a hole in the skull for medical purposes may seem as murderous as leeching or mercury cures, but archeological evidence of the practice has turned up all over the world, from South America to Scandinavia. Rumor has it the trepanning is still used in some New Age circles.
