THERE are quantifiable benefits often associated with taking up something like tennis and getting better at it. Your brain, it’s thought, will be recast and strengthened. Denise Park, a neuroscientist at the University of Texas at Dallas, randomly assigned more than 200 older people to different new activities for roughly 15 hours a week and found that only those who had learned and refined a complicated skill improved their memories. Other researchers say the intense and prolonged physical exertion of a game like tennis may fend off cancer by slowing the decline of your telomeres, the tiny caps on the ends of your DNA strands that tend to shorten and fray with age, and leave the DNA subject to greater risk of mutation during cell division and replication. You will, I am convinced, do good things for your heart: Senior Olympians have been found, on average, to have a cardiovascular “fitness” age 20 years less than their chronological age.
