Can’t resist - reminds me of the Frank Zappa song “Why Does it Hurt When I Pee?”
“Why does it hurt when I pee?
I got it from the toilet seat.
It jumped right up and grabbed my meat!”
People are so freaked out by germs because it was discovered by doctors many many years ago or so that by keeping places sanitary you had far fewer deaths and spread of communicable diseases.
And some people are such incredibly nasty creatures, I remember I worked at a toy store with a buch of mostly teenage employees and nobody would clean the bathrooms. They’d get fired before they’d do it. The 30-something managers had to do it. This was because sometimes the walls would literally be smeared with shit. Why, who knows, but somebody did it and I don’t want to touch anything they’ve touched.
Yes, washing your hands between dissecting corpses and delivering babies was just a great idea that took too long in the pipeline, but in more recent news, it seems to be the case that obsessive cleanliness might actually be a bad thing; low-level exposure to dirt and germs keeps the immune system drilled, ready to go and focused on the proper task.
