There is a great and widely revered myth in our society that flexibility is one of the benefits of youth and that, as we age, our range of motion is lost forever. Neither of these presumptions are true… at least not with the unwavering fatalism that we are taught. It is true that the body changes as we age. The tissue around joints thickens as cartilage decreases, affecting joint mobility. Muscle mass declines, reducing the strength necessary to support joints in their full range of motion.
