My roommate only washes up if he poops, never after peeing. Now every time I’m in any of the common areas I have to wash my hands after touching anything I haven’t wiped down. Thus, I wash my hands twice every time I use the bathroom; once as normal and again in the kitchen because I touched the taps, light switch and door handle in the bathroom which likely have groin sweat on them… /rant
Admittedly this post was more of a rant but it’s still helpful to know everyone’s answers. I major in microbiology and I know for sure that everything, everywhere is teaming with life and my hygienic habits are informed by that. One of my biggest reasons for wiping everything down all the time is to reduce the chance of spending three or four days in hospital shitting in a bucket and chugging gatorade. It’s unusual to die from a dirty doorknob (covid 3000 rubs it’s hands) but it’s not fun and a waste of time to be sick. Sometimes that’s unavoidable ofc, but I take pains to reduce my chances, even if it’s just a little.
