Growing Food

All the valium in the world would not calm you as much as growing some food. Working with plants has to be the most unwinding and relaxing things there is to do. It takes you right away from the stresses of everyday life.
But can someone please tell me why this isn't taught in schools? If you lived with a bush tribe in Africa, as a child all you would learn about is how to gather and grow food to survive. And those children are not obese, not violent, and for the most part are healthy. It would seem that drugs is the only choice when dealing with "attention deficit disorder" when it has been shown that planting and growing things is far more effective. Mean kids, small kids, boys and girls alike all do better when they are working with plants. And lets not forget the benefits of growing fresh food in the school, many children that are poor and do not have enough to eat will benefit greatly from this.
I know their are some movements taking place where this is starting to be done, in California there are schools ripping up pavement to plant things, as it has repeatedly shown to improve moral. If you are in a position to influence these kind of things, please try to. The world would be a much calmer and better place to live.
