It’s not uncommon for your memory to decline as you age and the process could start relatively early.
“Cognitive ability peaks in the late 20s, early 30s and starts to decline from there. It’s fairly normal to remember less in your 40s and 50s,” says Jeffrey Toth, Ph.D.
But brisk exercise that improves your blood flow — such as walking 30 minutes a day at a fast pace, biking or swimming — may be good for your cognitive health.
Physical exercise may make your brain more flexible and adaptable, which in turn could make cognitive training more effective, according to Toth, who is studying the effect of combining aerobic and cognitive brain exercise.
