In the book, The Naked Scientist by Chris Smith, he talks about how scientists have discovered the secret to living 14 years longer—by just doing 4 things!
"Researchers at Cambridge University have found the secret to living 14 years longer–don't smoke, drink moderate amounts of alcohol, exercise, and, above all, eat your greens!"
Professor Kay-Tee Khaw and her colleagues followed up with 20,000 men and women aged between 45 and 71 years old, who were recruited between 1994 and 1997. The study subjects filled in a simple questionnaire about their lifestyles and earned a point for every positive answer to being a non-smoker, light drinker, and regular exercise. They also earned point if a blood test revealed a Vitamin C level consistent with eating about five portions of fruit and vegetables.
Deaths amongst the volunteers were then recorded until 2006. When they analysed the results, the researchers found that, over an average period of 11 years, people who scored zero were four times more likely to die than participants who had scored four points. They also found that people scoring zero had about the same risk of dying as someone 14 years older than them who had a score of 4 points.
So the moral of this story is quit smoking, drinking in moderation, take the stairs not the lift, and follow the five-a-day plan (that's portions of fruits and veg, not hamburgers), and you might live 14 years longer.
