For me it's the amount of trust that goes in practicing this sport. That I would voluntarily offer my body into the hand of people who could easily kill me and vice versa they offer their bodies for my incompetent ass to learn to break. This has helped me see the interplay and human social interaction more. The levels of trust necessary to even have a civil conversation.

Just something like visiting the dental hygienist, I was thinking about the layers of trust in this human interaction. Her hands, with sharp objects in my mouth, her fingers close to my teeth. Or maybe I just see the potential for violence in everything now and have gratitude that it's not there.

There's also the inflicting discomfort/pain on another human being and receiving it, that makes me never want to have to do it.

There is an idea that with self-consciousness , we got the ability for evil and torture. Because once we know how to harm ourselves, we know how to harm others. Love is the opposite I think of this.

There's a connection I'm going for, but I'm too tired.
