A good way to have new ideas, it’s said, is to talk about the ideas you already have. After I posted about advantages of self-experimentation, Bruce Charlton, the editor of Medical Hypotheses, invited me to write an editorial about it. Wondering what I thought gave me some new ideas and the editorial turned into a full-length article called “The unreasonable effectiveness of my self-experimentation.” For 20 years I’d been mystified by this. I’m not exaggerating, I had no idea what I was doing right. I wanted to know — so I could do more of, or at least continue to do, whatever it was — but I just couldn’t figure it out.
