The ultra-health obsessed min-maxers I have met have been socially awkward to say the least. People who are fanatical about anything to the point it causes social conflicts strike me as compulsive. Some people just seem so obsessed about a single issue that they are burden to interact with, regardless of what the issue is.

There's nothing wrong with using soap every day, my grandparents have been doing it all their lives and they're healthy at their old age (90's). Plus you don't end up bothering others with your smell.

Or maybe stinks soundly.
