Rare hand washer here. I wash my hands if they’re visibly dirty, sticky or just feel grimy or gross. I try to remember before cooking for other people. After handling raw meat. In a public restroom if anyone is around to judge me.
That’s pretty much it. I’m gross and don’t think I’m superior in any way! I just have ADHD and forget/can’t be bothered. I never get sick, but I attribute that to a genetically decent immune system and not having daycare/school-aged children, who are disease vectors.
