Some may find this interesting: http://www.sfn.org/skins/main/pdf/neuromyth_busters/neuromyth_busters.pdf Myth: You only use 10 percent of your brain. Myth: Listening to classical music makes you smarter. Myth: Vaccines cause autism. Myth: Brain damage is always permanent. Myth: Your brain can’t make new cells. Myth: Drinking alcoholic drinks always kills brain cells. Myth: Drug use makes holes in your brain. Myth: Playing games keeps your brain young. I personally found the last myth the most interesting. They say "Truth: Crossword puzzles and similar games can help you learn words and improve specific skills, but they won’t enhance overall brain function. If you want to preserve your mental abilities, exercise your body. A healthy diet and regular exercise can help maintain memory and general cognition, particularly later in life. Starting habits that promote healthy cognitive aging early in life can preserve brain function during aging. Studies show that foods rich in nutrients and antioxidants appear to reduce the risks of age-related impairment. Aerobic exercise increases blood flow to the brain, and even lessens the rate of tissue loss during aging."
