Who would have thought it? Laughter, no surprise, is good for us. Buried within the paper:
While laughter may not be a panacea, there's still much to be gained from it. And, truth be told, there's room for plenty of additional chortles in our lives: Fry found that by the time the average kid reaches kindergarten, he or she is laughing some 300 times each day. Compare that to the typical adult, whom Martin recently found laughs a paltry 17 times a day. (Men and women laugh equally often, Martin adds, but at different things.)
Faith like a child, indeed.
