It's never too early or too late to start increasing and protecting your brain span. Certain cognitive functions may decline with age, but three decades of science tell us that core assets may be retained, regained and even strengthened across the lifespan.
As we age, the prefrontal cortex and the hippocampus, both of which are important for memory, planning, and learning, begin to shrink, along with a decrease in blood flow. But by staying physically and mentally fit, and continuing to challenge different sections of your brain, the longer you can keep it functioning.
