First, the next three chapters are queued up for this week. Second, I'm now the recipient of real science, and not fiction. I have red-green color blindness. For my birthday, my son got me a pair of Enchroma glasses. In natural light, I was totally shocked to find that they really work. Today is the first time I've ever seen the green shade of a traffic light - they've always been white to me. Welcome to real science!
