Ah, the good ol' days, where illness was caused by spirits and the best remedies included bleeding, alcohol, and cocaine! Things certainly have changed, but there are still some cultures that believe strongly in a spirit's ability to affect our health. 'Ghost Sickness' is a common belief among Native America Indian tribes, yet plenty of people from ALL backgrounds have felt a correlation between health and the supernatural. If you believe you are being made ill by a spirit...please lay off the cocaine. There are other ways to combat the problem!
