I like to put on hardcore when I have to clean my apartment, which I hate to do, but it's motivational. I like old heavy metal when I'm outside working on my car. Music has definite functions for me. ↗
I used to try to run five miles every other day, which I worked up to and I was doing it, but I was subjected to my own thoughts for forty minutes without any sensory input, and I couldn't stand what I thought. ↗
