Even better than music is putting on an hour of TED Talks on your smartphone whilst sweating away on the cross trainer. With music you can involuntarily make eye contact with someone you don't like, keeping your eyes on the screen helps with that. Nothing wrong with working out your muscles and brain at the same time.
When I was young, there was a god with infinite power protecting me. Is there anyone else who felt that way? And was sure about it? but the first time I fell in love, I was thrown down - or maybe I broke free - and I bade farewell to God and became human. Now I don't have God's protection, and I walk on the ground without wings, but I don't regret this hardship. I want to live as a person. -Arina Tanemura
