UNLESS you work a blue collar job, or any other job that requires you to be outside the whole time, I don’t see the point in showering every day. Especially if you work from home or in a building with AC. It seems excessive and is also a waste of water. But do what you want lmao.
Every human body is different. Some people need a shower twice a day. Some people have natural perfume.
If you are concerned about it being a waste of water, then you can campaign to make society treat it as a valuable resource and not a “free swimming pool for everybody” type deal. Cause for a lot of those cases you point out, people are just using it like it’s priced dirt low.
