At first I didn't get how this was an act of kindness. I had to actually go to the link above and read what they're trying to say. And then I got it. It's both a kindess to others and to yourself!
"At the height of laughter, the universe is flung into a kaleidoscope of new possibilities."
It can feel soooooo good to laugh. I mean really laugh! So it's good for you, right? And then, laughter is infectious, so it's good for others as well. I love it!
I firmly believe a sense of humor is essential for survival.
"So many tangles in life are ultimately hopeless that we have no appropriate sword
other than laughter."
~Gordon W. Allport
I would be remiss if I didn't leave you with a little humor:
"All my life, I always wanted to be somebody.
Now I see that I should have been more specific."
~Jane Wagner, The Search For Intelligent Life In The Universe, performed by Lily Tomlin
