Don't view this video unless you want to laugh. Once on this page you can scroll down a bit to read about the benefits of adding laughter to you day.
I'm making laughter one of my 52 healthy lifestyle changes, only this is one that I would call a default as I participate in the activity almost everyday. If I am having a 'down' day and if I have not actually had a good belly laugh, I will go to Just For Laughs on YouTube and find a few funny ones to get me laughing. These are just a small sampling.
