What is it about laughter that's contagious? Sometimes you just can't stop from smiling when you hear or see it. Last September, an elderly couple from Iowa infused the internet with laughter and joy. Their random act of happiness at Mayo Clinic hit You Tube and made more than 6 million people smile. And that, say Francis and Marlow Cowan, is what keeps them young.
Marlow and Francis are at Mayo Clinic giving an encore performance of an impromptu duet that went viral on the internet. People all over the globe watched it. "It's amazing to us how we could reach over 6 million people just doing a little piano duet. I think god has a sense of humor."
Dr. Paul Takahashi is a fan of the Cowan's. He says they've got it right - happiness, being active and staying connected help you live longer. "The cowans have very positive energy. People who are positive tend to do a little better over all in life and that's been studied. People tend to live a little longer and live a little better when they're positive."
Being positive, happy and active as you age will certainly help you meet people and make friends, but it's also good for your brain and body. It keeps your brain in shape by activating brain cells called neurons and it improves blood flow which is good for your blood vessels, muscles and organs.
Love and laughter and the Lord. That's what the cowan's say has kept them going through decades of marriage. "When was it? Oh, geez, i don't know when it was it was a long time ago. 63 years." And through all those years they spread that joy. And in the process have made millions of people smile.
