Yes, I’m not arguing that. There’s a whole lot of emphasis on “propere hygiene”, it’s not just “showering a lot”.
Sometimes excessive showering can cause your skin to lose it’s “natural” properties and bad bacteria might set up colonies, and then the overt showering will keep the natural skin balance from balancing itself.
Also, diet affects one a lot.
I don’t think everyone who sweats, smells. And some sweat smells straight up good. (Again, given proper hygiene, and this good sweat smell is usually connected to intimate activities.)
