It’s all relative tho isn’t it? I imagine there are places in the world where people don’t change their underwear every day.

I expect there are people who look at your once a day and think… that’s filthy. Maybe they change their underwear after each trip to the toilet. Everyone presumes their behaviour is normal and judges accordingly, but it’s absolutely subjective.

And perhaps there are ecological arguments for not constantly washing clothes. Water waste. Electricity usage. Carbon footprint etc.
