If you want to improve your life expectancy you can do the sums and see just how much extra time you can have according to Scottish researcher Dr Peter Joshi.
Obesity levels are now three times more than in the 1980s. At that time six percent of men and eight percent of women were affected. This has spurred an Edinburgh team to look into the genes affecting longevity in families and the lifestyle factors that affect life span in individuals. The old nature/ nurture debate again. Overall 600,000 people were tested and their family histories explored.
When it comes to longevity the balance comes down much more to lifestyle than your genes.
Educate yourself: add a year to every year educating yourself beyond school. That’s really like going to university for free. You get the time back at the other end!
Get slim: add a year for every surplus stone you lose. Diabetes complications is the main factor in causing the reduced life expectancy.
Stop smoking or don’t start: add seven years to your life if you don’t smoke those 20 cigarettes a day.
Praise the parents: some people have a gene that improves their immune function giving an extra six months life expectancy.
Blame the parents: Addiction to drugs and alcohol are somewhat genetically based.
Blame the parents (again): A gene that affects cholesterol reduces lifespan by about eight months.
