Movement and fresh air In the fresh air, the blood is more actively saturated with oxygen, faster carries oxygen and nutrition to the brain cells, the processes of oxidation and metabolism are intensified, and the energy we need so much is released. The brain makes us move in order to keep ourselves and us. Give pleasure to think, create, solve complex problems, have memories. There is no movement of fresh air, the blood turns sour - the brains "turn sour". #RandomThoughts
