Reply to comment by TheReal_AlphaPatriot in TIL your computer keyboard is 20,589 times dirtier than a toilet seat. The average office keyboard has 3,543,000 colony-forming units (CFU) of bacteria per square inch while your average toilet seat only has 172 CFU per square inch by SappyGilmore

Exactly. The bacteria got onto your keyboard from your hands. The same hands you'd use to rub your eyes, or pick a popcorn kernel out of your teeth.

It's just a stigma like with saliva. We spend all day swallowing our own saliva. But if we spit into a glass and drank it out of there, it would be gross for some reason.
