Speaking of cleaning your ears. Ear candling or coning is ineffective.
Ear candling or coning is a method of cleaning the ears and the mind, which allegedly alleviates a host of physical, emotional and spiritual ailments. A hollow candle is stuck into the ear and lit, allegedly sucking out earwax and negative energy. The process is ineffective for earwax removal. I don't know how anyone knows whether it sucks out energy, positive or negative.
What wax appears in the cone is from the melted candle, not from the ears. The suction created by the coning flame is insufficient to remove wax, which, by the way, is good for you. It traps dust and dirt and helps fight infections.
Though some people fear that coning will leave them mindless, the only real dangers are from burning, infection, obstruction of the ear canal and perforation of the eardrum.
