A famous playwright once wrote the words, "with mirth and laughter let old wrinkles come," which translates, to me at least, that one's life should be filled with happiness, enjoyment, a good nature and laughter until the end. I can't ask William Shakespeare if that's what he truly meant and he can't correct me so I'll run with it.
There's health benefits to laughter, or so I'm told, and I think anyone who has laughed with abandon and without constraint might agree; it simply feels good and I believe there is not enough laughter in the world right now and that the people of the world actually need a little healing.

The most important person in my life makes me laugh all the time in a lot of little ways, some big ones also and sometimes in the most inappropriate ways and places, but it's that sense of humor that attracted me in the first place and a life full of laughter feels right to me, like I'm spending life well and with the right person.
If the world, the people of the world, had more laughter and joy, it wouldn't look the same as it does today, it would look better and be better, and I believe each and everyone of us have a responsibility to bring that joy, happiness, humor and laughter to every day we live and to as many people as possible.
