I rarely do either. I cannot remember when I last actually laughed out loud. But I did snigger a couple of times during a comedy spoof film a while back. As for crying, the last time I cried was when my birdy died five years ago, and before that it was probably decades ago.
I laugh daily, literally. A day without laughter is wasted.
As for the other -- four years ago when my mother was on her deathbed she made me promise I wouldn't cry. The question of whether I managed to keep that promise is, to use one of her favourite words, "iffy".
I suspect though that in general as we age into the old codgers we are, those peaks and valleys of emotions flatten rather a lot. But I like to cultivate the positive. I admit, I like the endorphin rush.
