I, myself, am no youngster. I never used to have to worry at all about counting calories and staying fit and slim. BUT, as the years go by the metabolism slows and the pounds are harder to keep off. This is especially true if an appreciation of good food and wine have become a form of socializing and entertainment.
No matter what your age, exercise has been proven to be the closest thing to the Fountain of Youth (plastic surgery notwithstanding). It has been shown to improve breathing, circulation, bone density, ups the metabolism and keeps the joints moving. For me, Pilates works and it’s something I can do well into old age. I found this great article at USATODAY.com that made me smile. Maybe it will do the same for you.
