I guess it’s cus everyone has a different standard of what pollution is for them. For me, the sound of windchimes calm me, I find industrial air vents relaxing, and church bells oddly peaceful, but can’t stand someone even driving near me, dogs barking, babies crying, or fluorecent lights flickering. But you know, people need to drive, dogs and babies need to talk, and the world goes on.
I didn’t use to either shower or bathe but it was a mental health issue: I went though both depression, which didn’t help, and I didnt have good showering habits due to being kinda aquaphobic. If water hit my face at all I would think I’d die (pretty dumb I know). Nowadays I bathe pretty much daily. Having a detachable showerhead helps a lot so I don’t have to deal with water on my face.
