Well, we knew it. Now the studies confirm it. Vigorous walking for an hour a day five times a week can chop a dozen years off the biological age of people 64 and older, according to Roy Shephard, M.D., Ph.D., of the University of Toronto, reported online in the British Journal of Sports Medicine.
A review of recent studies in patients age 64 and older showed that such a regimen can boost maximal oxygen intake by about 25% within three months, effectively decreasing biological age by about 12 years. That sounds good to me!
