How Much Brain Do We Use?

For my birthday, my daughter Tamar gifted me a book, “Keep Sharp. Build a Better Brain at Any Age” written by Sanjay Gupta, MD. Besides other medical occupations, Dr. Gupta serves as the CNN chief medical correspondent.

You may have heard that humans only use about 10 percent of our brains. Turns out, this is a myth. To make his point, Dr. Gupta compared the brain to a town. “The important structures such as the homes and shops are in nearly constant use, and they probably represent 10 to 20 percent of our brains. The rest, however, are the roads that connect all these shops and homes. Without the roads, the information could not get where it needs to go. So while the roads are not in constant use, they are necessary.”

You can learn about other myths about our brains and exercises to keep you sharp in the book. Meanwhile, you can also exercise your brain by reading jokes to your friends in “42 Encounters with Laughter”. And of course, also enjoy watching birds, as these birds that I encountered during my recent trip to Palm Springs.

Enjoy and Share with a Friend!
