You can use regret and counterfactual thinking to understand some of the mystery of that horrible disease of scitzophrenia. And in some ways, this philosophy of no regrets, that if you actually don't have regrets, that might be a marker for a serious problem. I mean, literally, it couldn't meano, i don't experience regret. Ok? Well, maybe your sociopath, or maybe you're five or maybe you have lesions in the orbital frontal cortex of your brain. That was, that was such a good example. I, that's tho, what i all steal. So thanks.
