Ditch the GPS

It can age-proof your brain. ”Finding a new way to get to a place you visit often, without using GPS, creates more connections that enlarge your brain’s hippocampus, shrinking the risk of memory loss,” says Dr. Roizen. Also smart: playing brain games like sudoku, crosswords or those at Brain HQ ($5 a month, AARP.brainHQ.com) for 20 minutes a day. In a 10-year study, this type of training cut dementia risk by 48 percent.
