Like your muscles, your brain gets flabby if you dont exercise it. To find out the best ways to strengthen your brain, take Healths anti-aging quiz (below), developed with Louis Cozolino, PhD, a professor of psychology at Pepperdine University and author of The Healthy Aging Brain: Sustaining Attachment, Attaining Wisdom (W.W. Norton, 2008; $35).


1. Which is better for keeping your mind sharp?

B. Playing Scrabble with your kids.

Answer: B. Interacting with your kids, as opposed to sitting passively on the couch, triggers neural growth.

2. Which prevents you from getting lost?
A. Taking unfamiliar routes to work, home, and the grocery store.
B. Taking the same route so its ingrained in your brain.

Answer: A. Mix it up. Repetitive routines tell your brain that it no longer needs to keep growing.
