Nope, I’m an IT guy with a nurse for a wife. I’ve taken first aid (including proper handwashing) for about 30 years being a member of St. John’s ambulance for a long time in there.
It’s been beaten over my head for most of my life. Looking into it, the rabbit hole goes deeper. I also found a TED style talk (may have been TEDx? I forget) talking about the best way to dry your hands while using as few paper towels as possible.
I know I’ve only really scratched the surface with what I could know on the topic. I also understand that there’s helpful “germs” on your skin, and over washing or over use of hand sanitizer can be detrimental to skin health and long term health; of course with a huge number of caveats that are just so far outside of the scope of what I’m trying to say.
Looping back on topic, I’m a science nerd, first-aid trained, very curious and knowledge seeking individual with a large exposure to medical people. Hygiene is very important.
