Yes guys. I ain't kidding... Airborne bacteria from a flushing toilet can reach a toothbrush placed within six feet.
"A study published in the journal Applied Microbiology in 1975 (before the adoption of low-flow toilets) found that whatever you put in your toilet can stay there long after you flush. After seeding a toilet bowl with potentially infectious bacteria and viruses, the researchers found that the toilet dispersed the microbes far enough to settle on other bathroom surfaces, like the floor, the sink, and even your toothbrush."
CLOSE THE TOILET SEAT!!!
