36. Sanitize a Toothbrush

According to a University of Manchester study, about ten million tiny bacterial tenants are living in your toothbrush bristles and vacationing on your bicuspids every time you brush. Serve them an eviction notice by rinsing the toothbrush under the tap and storing it upright to dry. Then swish the bristles in mouthwash for 30 seconds to really send bacteria packing.
