If you pay attention to the news, you will often hear pseudo-scientific misleading statements like:

“There’s more bacteria on your smartphone than on your toilet seat!”

replace smartphone with keyboard, mouse &c. Oh really? If toilet seats are so clean lets see you eat your dinner off of them then (Clearly, no sane person would do this for a number of reasons. I’d wager people would in fact eat off their smartphones instead. Why? There’s probably a psychological component to it). You know what’s got more bacteria in it than a smartphone? You. 10% of your body weight is made up of bacteria, bacterial cells out number human cells. Does this mean we’re all about to drop dead at any given moment? Evidently not, well not because of the everyday bacteria present in our bodies anyway.

The number of bacteria is not important, it’s the type. The pathogens that hang around the bog seats are a lot more dangerous than the ones on our smartphones and other household objects. That’s why you use bleach on the toilets and maybe a wet wipe for your phones. There’s good bacteria and bad bacteria.
