The toilet’s probably the cleanest part of the day.

From the article:
His studies have found that on the average toilet seat there are 50 bacteria per square inch.
"It's one of the cleanest things you'll run across in terms of micro-organisms," he says. "It's our gold standard - there are not many things cleaner than a toilet seat when it comes to germs."
We should be more worried about other household items, it seems.
"Usually there are about 200 times more faecal bacteria on the average cutting board than on a toilet seat," he says...
In other words, a kitchen sponge is 200,000 times dirtier than a toilet seat, and a dishcloth is 20,000 times dirtier.
This is the same the world over.
To be fair, he's not talking about public toilets, but it's still interesting. Public toilet seats would of course be cleaner without hoverers.
