When you reach your forties, exercise becomes more important to retain your youth - both of the body and the mind. At this age, most people (according to surveys we have run here on Cognitive Labs) start to think that longevity is important. In fact you can start being proactive by creating a memory baseline here, or even, if you like, read more about Alzheimer's (the information comes from the National Institutes of Health) Guess what? Playing games can also be helpful, plus a variety of things like reading and crossword puzzles and even action games, which have been shown to improve reaction time by up to 100 milliseconds. Get a quick measure using our speed test. Faster reaction times, in several studies, have been connected to longevity.

Take the tests and play the games that interest you. The games are unlimited once you've registered - all selected by our editors at Cognitive Labs Game Central.
  Either way, you're making a smart decision.
