We are just not as fast as we once were. Also, not all memory tasks diminish. Remembering historical facts, for instance, may actually improve. What's most important, however, is that age related memory loss may be slowed down to a trickle by applying specific memory strategies, says Dr. Robin L. West, a University of Florida psychologist. These include, eliminating distractions, focusing your attention, organizing the information to be remembered and relating it to something you already know, writing down and linking main points, planing recall cues, relaxing, take your time, and practice.
Physical exercise is necessary too.
It increases the flow of oxygen to the brain and helps to maintain your health. Drug interactions and side effects can play havoc with successful remembering.
