I take a walk in the woods nearly everyday, to walk my dog. I've always known that I love going through the forest, but I never really thought about why. This article that I found, Back to the Forest, talks about why being in the forest is good for your health, and for your happiness.
It says that being in the forest is good for your breathing (oxygen from all the trees), it's good for your concentration, co-ordination, and meditation. It talks about a lot of other benefits as well, including your happiness and calmness. The article says that it's also very good for a person to be surrounded by the natural beauty of the world.
I liked this article because it gave just enough description of each benefit of being in the forest, and it made me want to spend even more time in the forest then I already do.
