I guess it was Kermit the Frog.

That said, It's not easy being green, but I'm here to tell you that being green can help you live longer.

There's plenty of data to show that we living creatures need to be spending time outdoors, and we just don't get enough of it.

There was a study out of Harvard and Brigham and Women's Hospital.

They looked at 100,000 nurses over many, many years, and what they found was that women who lived in the greenest areas had a 12% reduced risk of early death as compared to women who did not.

They found lower rates of certain types of mental illness, lower rates of depression, lower rates of anxiety and just lowered their rates of some of these mental illnesses.
