JJ, at our age any special care of the Achilles tendon is extremely important. Mine bark at me more often than I care to admit. But it usually means I have to shut down for a short time. My wife and I are prolific walkers (many miles a day and week) and yoga enthusiasts. So I know my legs are strong, but I also know an Achilles injury, at my age, could take forever to heal and I may never be quite the same.
