When it comes to getting older, most of us react in one of two ways: Fight it tooth and nail, surrendering a good deal of self-respect in the process, or simply give in. There has to be a better way — a path to stay spry, healthy, even fashionable — despite the birth date on your driver's license. To find it, we cast a wide net, consulting with wellness experts, trainers, exercise physiologists, nutritionists, health coaches, stylists, and barbers. Not one suggested plastic surgery, a daily dose of HGH, hair plugs, or CrossFit. What they did recommend were ideas that, done regularly, will not only reboot your health, fitness, and style — but will also change the way you feel about your age. Not that you'll look it.
