Have you seen this spoof ad for Nature?
It is a parody of drug commercials that promotes getting outside in nature. I know that I need time outside on a regular basis. I need to breathe fresh air. When I spend too many days inside, I get cranky, and one of the best ways to un-cranky myself is to take a walk in nature.
There are lots of benefits to getting outside, as it improves physical and mental health. This article from Care.com says that the health benefits of playing outside include:
Improving vision
Promoting social skills
Increasing attention spans
Reducing stress
Enjoy the video and then get into nature. Better yet, skip the video and go outside. I, myself am off to hike the Wissahickon or maybe walk the Schuylkill trail. Get some Nature. Its good for you!
