It makes me queasy to think how many trillions of bacteria are both in and on us. Worse is that some bacteria are holding back even worse bacteria from hurting us. Most bacteria aren't pathogenic, aren't going to infect us (make us sick).

Although...faecal bacteria are mainly pathogenic and many food-borne bacteria are pathogenic. I had a batshit crazy housemate that finally left last month who would use the bathroom, open the door, THEN wash her hands without soap. shudder and she didn't shower, and she had two cats that she let shit all over her room and not clean out the litter box for days. I felt like I was closer to cellular death machines than being in the lab working with bacteria. I'd take the lab with my PPE over living next door to that trainwreck any day.

Anyway, just remember to wash your hands with soap, wash/rinse your veggies, don't leave food out of the fridge for longer than two hours, and for god's sake stop touching your eyes without washing your hands first. Get some eye drops and stop rubbing them.
