Myths that have been debunked, or should be:
Lemmings do not commit mass suicide, as depicted in Disney movie White Wilderness.
Opossums do not feast on ticks. Studies show the only ticks they consumed were as a result of their grooming themselves.
"Your mattress collects 8-9 lbs. of your dead shed skin cells per year."
Evidently this statistic has not yet been debunked, but it should be. Though true that humans shed their skin cells, I contend showering or bathing on a regular basis would wash away a lot of shed skin. As for the skin collecting in mattresses, aren't mattresses mostly covered by at least a sheet, usually a fitted bottom sheet, most often in addition to a mattress cover. Assuming the bedding is laundered on a fairly regular schedule, how would the skin cells find their way through to the mattress. And since most people wear pajamas, nightgowns or nightshirts to bed, those determined skin cells would have to traverse through showers, jammies, sheets and mattress cover to penetrate or settle in or on your mattress. I cry false information, most likely promoted by mattress sellers.
