Everything is has more germs than a toilet seat

I wish people would stop using toilet seats as the ultimate benchmark for germs. Germs require debris to replicate and thrive, your average toilet seat is a smooth surface with usually nothing worse than a splash of sterile urine to contend with.

So just about every surface with nooks and crannies is "dirtier than a toilet seat". Particularly if they collect human debris. That includes keyboards, your mouse, your desk, the bit behind your monitor and the even the back of your hand.
