Thirty odd years ago, when Sweet Bear and I first met, I was having a rough patch and he offered the following advice, "if you can't remember the last time you laughed, it has been too long." I knew he was a keeper at that point. Doc Spo says that watching an old Marx's Brothers Movie is often as helpful as a prescription, and cheaper, his favorite is Duck Soup.
So wear the silly T-shirt, watch the comedy, or offbeat show. You Tube is filled with short videos of classic comedians - I was watching those on the treadmill in the gym one morning recently, laughing out loud with headphones on so I didn't realize how loud I was. A neighbor came over and said, I need to watch what you are watching.
I get emotional watching movies, there are times when I feel so much better for having cried through a movie. Maybe it is feeling, maybe it is chemistry, but at time I really need to re-watch "On Golden Pond" to feel what living a long and full life is all about.
When life is boring, so something, see something, read something, hear something, that moves you. It is good for you.
