Exercising your brain can improve your intelligence.
Exercising your brain can improve your intelligence.

Your body has 206 bones, 600 muscles, 22 internal organs and 100 trillion cells. Your brain contains 100 billion neurons, 900 billion glial cells, 100 trillion branches and 1,000 trillion receptors, all interlaced through a complex network. Many of us spend several hours a week at the gym exercising our bodies, but what about exercising our brains?

You might already know that exercising your brain, no matter what age you are, can help to improve your intelligence. But did you know that it can also help to prevent dementia from developing? If puzzles aren't your thing, try video games (choose those that emphasize dexterity skills) or something simple such as taking a new route to work. Consider getting both your body and brain in on the action. Dancing requires your body to move around -- physical fitness -- while your brain is forming new pathways as it learns and recalls dance steps -- mental fitness.

Your new fact for today: Take advice from real age expert Dr. Oz -- eat foods high in selenium, a mineral that could help keep your brain young. Try blueberries, a superfood that's shown to be beneficial for preventing and slowing neurological aging.
