Your Mind Is Declining
Starting in your 20sónot old ageóbehavioral evidence suggests that you enter a linear cascade of general cognitive decline. (Yes, it's depressing. No, the claim isn't based upon some quack study.)
This decline is notably seen in tasks that are highly mentally demanding, like speed of processing (how quickly you handle incoming information), attention, working memory (how well you manipulate and keep information active in your mind), and, of course, long term memory.
In real life, these effects are seen in everything from how long it takes to learn a new skill to how quickly you can recall a factoid. They're with us all day, every day.
Humans, of course, are adaptive creatures, and the human mind is the most incredible biological machine in existence. All hope is not lost. We already develop coping mechanisms, and expanded experience often minimizes the impact of our declining cognition. (Experience is represented by "world knowledge" on the graph above.) But in an era during which anything seems possible, could we significantly alter the course of this graph?
Could we make the three green, three blue and four grey lines stay level...or even go up?
What You Can Do About It Now? There's a simple mantra in circles of cognition psychologists: "Use it or lose it."This Is Your Faulty Brain, On a Microchip - Memory forever - Gizmodo
