You and I have known for some years now that laughter is very good for you, but scientists, being very serious persons, have only recently found this out to their satisfaction, as detailed with no sense of humor:

"The endothelium has endorphin receptors so what may be happening after a good laugh is these endorphins are released and activate the receptors, causing an interaction or perhaps just an independent dilation of the endothelium. This increases blood flow, which is good for overall cardiovascular health. It's also possible that mental stress may lead to the release of stress hormones such as cortisol, which may then reduce the release of nitric oxide from endothelial cells. This, in turn, could result in constriction of the vessel and the endothelium is the first line in the development of atherosclerosis or hardening of the arteries, so, given the results of our study, it is conceivable that laughing may be important to maintain a healthy endothelium, and reduce the risk of cardiovascular disease,…"

Doesn’t make me laugh. Not a chuckle, even in the footnotes.

For laughs, I’d rent one of these. (Do you believe no After Hours??)
