I used to write with my left hand for many things thinking that I would make the right side of my brain be more active and have more creative thoughts. It was an experiment that went on for several years when i was a messenger and I had a manifest that I had to fill out, it was real messy.
Yeah I was into a lot of biofeedback ideas and trying to hack my brain by changing your normal behavior. Most of the things you change go back when you stop doing those things, but sometimes things stay with you. I am much more empathetic now than I used to be.
