Can a healthy lifestyle add 12 more years to your life?

That's the possible conclusion from a big study in the US by Harvard University. The study analysed the medical records of 123,000 volunteers. The five healthy lifestyle factors they researched were never smoking, a healthy BMI, moderate to vigorous physical activity, moderate alcohol intake, and a high quality diet.

The projected life expectancy at age 50 years was on average 14.0 years longer among female Americans with all 5 low-risk factors compared with those with zero low-risk factors; and for men the difference was 12.2 years.

It's research like this which makes it so important for government, businesses, employers more generally and health professionals to make healthy choices the easy choices for people - and for each of us to play our part by giving higher priority to following healthy lifestyles.
