I can’t sleep, so I’m reading articles on the epidemiology of chronic diseases. You can learn a lot just by reading some of this stuff, like the fact that heroin and ketamine are the most used drugs in SE Asia, and that 60 percent of the world dies of cancer.
Superstitious conditioning: when a behaviour is reinforced despite the absence of a real relation with the “reward”. I suspect I do this. Possibly with worrying and things going well. Because I worried last time, and I got an A, I worry more to get more As, despite the fact that the A is due to hard work, not to worry. As human beings, we’re very silly and plagued by spurious thinking. Alas.
