I wash my hands more than 20 times a day. Not compulsive. I get my hands dirty. I push elevator buttons with the end of a pen AND I do not touch anything in public restrooms. Since I implemented those policies I rarely get sick.
Seems like a reasonable approach.
Since I retired and have much less contact with people in general, I’ve noticed a BIG reduction in getting colds.
I’ve heard the credit card signing stylus at stores are some of the worst for germs, so I’m careful with those.
