Those who live the longest are active with growing their own gardens and doing their own housework. They have a sense of purpose in life, which is worth seven years of extra life expectancy. They practice their own methods of stress reduction. They eat their smallest meal between 4 and 6 p.m. and don't eat any more the rest of the day. They drink one or two glasses of wine per day with friends and/or with food (Adventists excluded). They attend faith-based services four times per month, adding four to 14 years of life expectancy. They keep aging parents and grandparents nearby or in the home. (This lowers disease and mortality rates of children in the home, too.) They commit to a life partner, which can add up to three years of life expectancy, and invest in their children with time and love. They chose — or were born into — social circles that support healthy behaviors. From his book, "Reverse Engineering Longevity", Dan Buettner says they have a "Plant Slant." They eat beans, including fava, black, and soy,as well as lentils — the cornerstone of most centenarian diets. Meat —mostly pork — is eaten on average only five times per month. Serving sizes are 3-4 ounces, about the size of a deck of cards.
