Deodorant and daily showers are almost uniquely American concepts.
Travel the globe and smell how 99% of humanity smells. You get used to it.
We were at an outdoor festival in Deidesheim Germany 1980. It was cool and rainy. The sun came out and everyone took off jackets. The BO was horrible. We had stayed at a friend’s house there for a week. I was the only one who took a shower that whole week. Some of the people traveling with us were from Houston. Still, no showers. When in EU do like they do.
A friend had a foreign exchange student from France. He didn’t bathe or use deodorant, wore same shirt all the time. She worked on him for a year to bathe more often, and to change shirts.
Yep, that’s the reality of it. And some cultural diets and occupations can may it even worse.
