Want to live to be 100? Many people believe that eating healthy such as a Mediterranean diet and getting the proper amount of exercise are the keys to longevity. Although they help, part of it is in the genes and women have a much better chance of hitting this milestone. Men in their 60’s have a 3.4 chance of making it to 100 compared to 6.5% for women. But your genes also play a big part. The New England Centenarian Study found 281 genetic markers that predict with 61% accuracy who will reach their 100th birthday. Interestingly, about 85% of centenarians live in cities where there is better access to medical care, social networks, culturally stimulating and transportation systems. Social interaction is also important. A study from United Healthcare found that 87% of centenarians communicated nearly every day with a friend or family member. Attending religious services also has an impact.  Going to church four times per month has been linked to a four to 14 year increase in life expectance (AARP Bulletin August/September, page 47).
