Small changes 'add years to life'

A Cambridge University study looked at over 25,000 people. It found that stopping smoking, exercising more and eating better could give you the life expectancy of a person 11 to 12 years younger. The participants have regularly filled in questionnaires about their diet, lifestyle and health and had periodic check-ups from nurses. These latest results from the study showed eating five portions of fruit and vegetables a day can give you the life expectancy of someone three years younger. Not smoking turned the clock back by four to five years. Even increasing exercise by a moderate amount can take up to three years off. But the amount of exercise someone would need to do to achieve that depends on their job.
