Brain Power Plants

Did you know that physical exercise can help to keep your brain younger? Studies show this may be because working up a sweat improves your neurons' power supply, which in turn encourages the growth of new neurons and allows the brain to work faster and more efficiently. In response to exercise, your muscles produce new mitochondria, miniature power plants inside cells that supply the body with energy. Neurons ten to lose mitochondria with age. Increased mitochondria may help the brain slow down declines in brain function due to age and disease. http://www.scientificamerican.com/article.cfm?id=how-exercise-jogs-the-brain
