Memory loss is the single biggest fear for Americans over the age of 55 and it's understandable for over 4million currently suffer from Alzheimer's Foundation and those numbers are expected to quadruple by 2050. Sudoku, crossword puzzles, Ginkgo infused soft drinks, celery and a like dont have enough evidence that any of these things really work.
Infact, there's only one practice that's been proven, without question, to preserve your memory: exercise, "Aerobic activities tend to show larger effects than non-aerobic activities," University of Pittsburgh psychologist Kirk Erickson.
Working up a sweat helps your mind stay fit better than any crossword puzzle-unless you're doing that crossword on a treadmill. Just walking 6miles a week can ward off memory disorders caused by aging. Found out that those who walk 6 and 9 miles a week - whether to work or with the dog - had half the brain deterioration of those who didn't. "Exercise seems to enhance some of the more fundamental properties of our brain and it increases the growth of new cells and improves cellular processes associated with learning memory". To put it simple, walking keeps your gray matter from shrinking, and the more matter, the more mind.
