I want to know: Does laughter cause gene expression? This is a question I have never heard asked. If there is a psychologist or neuroscientist in the audience who knows if this question has ever been asked, I want to know that, also. The answer is certainly, Yes. Of course, there are genes constantly activated by everything we do. But are there specific genes associated with laughter? This is not a subtle question, such as the difference between humor and laughter. I am talking about Hee-Haw, robust, in yer face, I can’t stop laughing, lol catz!
