Odd - The Worst...

The worst place for your toothbrush: on the bathroom sinkThere's nothing wrong with the sink itself — but it's awfully chummy with the toilet. There are 3.2 million microbes per square inch in the average toilet bowl, according to germ expert Chuck Gerba, PhD, a professor of environmental microbiology at the University of Arizona. When you flush, aerosolized toilet funk is propelled as far as 6 feet, settling on the floor, the sink, and your toothbrush. "Unless you like rinsing with toilet water, keep your toothbrush behind closed doors — in the medicine cabinet or a nearby cupboard," Gerba says.

The worst stall to pick in a public restroom: the one in the middle The center stall has more bacteria than those on either end, according to unpublished data collected by Gerba. No, you won't catch an STD from a toilet seat. But you can contract all manner of ills if you touch a germy toilet handle and then neglect to wash your hands thoroughly.

The worst place to pick up a prescription: the pharmacy drive-thru In a survey of 429 pharmacists, respondents ranked drive-thru windows high among distracting factors that can lead to prescription processing delays and errors, says survey author Sheryl Szeinbach, PhD, professor of pharmacy practice and administration at Ohio State University. If you don't want to give up the convenience of a rolling pickup, be sure to check that both drug and dose are what the doctor ordered.
