Most of my washing routine is actually for chronic pain. I don’t need to scrub for smell too much, but hot water feels good on pained areas.
I had not heard this one before, though I have looked into atonal music one time in the past. This is certainly the most unsettling piece I have ever heard and it is amazing. Thank you for sharing the link.
