To begin, go to the Blue Zones website at www.bluezones.com. There, you’ll find the Vitality Compass™, a tool that asks you 33 questions and, based on your answers, calculates 1) your potential life expectancy at your current age, 2) your healthy life expectancy—the number of good years you can expect to live, 3) the number of extra years you’re likely to gain if you optimize your lifestyle, and 4) a customized list of suggestions to help you with that plan.
