...Is Adam S (first double winner of the e-factoid - woohoo!). Here is his triumphant titbit:
"A surgery that dates back to prehistoric times, Trepanation is the grisly, gung-ho practice of drilling into the skull of a sufferer of mental disorders; ostensibly to 'allow evil spirits to escape'. A more scientific (but unverified) rationale for this practice suggests that brain blood volume may be increased by freedom from the skull’s enclosure. Seemingly misguided and brutal, trepanation is astoundingly alive and well - the documentary 'A Hole in the Head' documents the three attempts of Joey Mellen to drill a dime-sized hole in his skull with a power drill in a gruesome endeavour to 'raise his consciousness'."
