So many of us work indoors all day long and although we may see the sunlight, we are never in it. Taking a walk outside is good for our emotional, mental, and physical health. Like the song, Walking in Sunshine, says, "Don't it feel good?" There is a reason; you get Vitamin D from the sun.
Several of my friends take daily walks (with or without pets as a reason to step outside) and they all swear that their daily walks are essential to their well-being. It's an easy and accessible exercise that nearly everyone can do anytime. With the price of gasoline these days, some people make their walks a productive means of accomplishing both exercise and transportation goals at the same time; if you are heading to the market a few blocks away for some bread, why not walk instead of drive?
There are also many causes that sponsor walks as charity donation vehicles, so if you want to add even more value to your walk, sign up and get people to sponsor you; what could be better than being paid to walk?
