Could you live to 100? Take the quiz

We all know our lifestyle has an impact on our health and wellbeing, but according to Dr Thomas Perls, director of the New England Centenarian Study, you can estimate exactly how the effects of your choices (healthy or not) will add up to determine your life expectancy.

Did you know a stressful lifestyle could knock three years off your life, or that not having family living close by could lose you a year? Or that suffering gum disease can have knock-on consequences, so that forgetting to floss daily will strike another year off your life? Even your wake-up choice of morning coffee (known to exacerbate some health conditions) over tea (packed with antioxidants that boost immunity) could affect the age at which you die.

The good news is that you can do a great deal now to increase your chances of a long life. See how you're doing so far by completing our quiz (below). Start at age 89, then add or subtract years as directed when you answer yes or no to the questions. For a more detailed assessment of your health and your life expectancy, visit www.livingto100.com.
