Study: Quit smoking, exercise, and going out adds 5-6 years to life

Not that it's a surprise, but eating healthy food, exercising and having a social life is good for your health. BBC News:

They showed that smokers died a year earlier, but people who quit in middle age were almost as long-lived as those who had never smoked.

Swimming, walking and gymnastics increased life expectancy by around two years. People with a rich social circle lived a year and a half longer than those without.

Combining figures for healthy, low risk, lifestyles showed men could extend their lives by six years, and women by five years, by adopting the most healthy options.

I was always impressed with Jojo's French grandparents, who even into their 90's would take a walk every day. Both ate well, enjoyed having family over and led very actives lives. Genes surely had something to do with it, but it didn't hurt that they were disciplined at the table and kept active. Even after her grandmother had hip surgery in her late 80's, she was back walking within two months.
