Its more common when you need to take a farmers bath.

Interesting, I didn’t know about that term at all. What’s a farmer’s bath, some kind of deep-wash, basically?

You sterilize because the main cause of stink is not dirt or oil or sweat but microorganisms. […] Soap does not kill microorganisms very well on its own, instead it helps the water pick them up and wash them away

Which is why I mentioned soap as a degreasing agent, removing oils and the vast, vast majority of microorganisms with it, alongside water and friction.

Also about the surgeon thing I’m pretty sure they still use sterilized gloves in a sterilized environment with equipment that’s been through riggerous decontamination.

Because they’re gonna play with your insides, where the smallest thing could infect and kill you.

They probably use hand sanitizer too lol.

While washing their hands with soap and water?
