The problem that technology presents us is that it increases the amount of information at our disposal, but slowly degrades the power of our memory to retain it. Tasks that used to exercise the brain―remembering phone numbers, doing simple calculations, navigating and remembering streets in a city―are now performed for us, and like any muscle the brain can grow flabby from disuse. To counteract this, in our spare time we should not simply look for entertainment and distractions. We should take up hobbies-a game, a musical instrument, a foreign language―that bring pleasure but also offer us the chance to strengthen your memory capacities and the flexibility of our brain. In doing so, we can train ourselves to process large amounts of information without feeling anxious or overtaxed.
