Researchers have identified 9 key factors to longevity. Here are their details for your benefit


Melbourne: Health experts have analyzed “blue zones” around the world and come up with two main factors that increase our longevity – having a healthy lifestyle and a reason to live.
According to, led by American researcher Dan Buettner, these “blue zones” were analyzed by a team of specialists, including doctors, anthropologists, demographers, nutritionists, and epidemiologists, to see why their residents seemed to live longer.

The researchers identified nine key factors to longevity:

* Intense and regular physical activity while undertaking daily duties. These people do not live a sedentary lifestyle.

* Reduction of stress, which can involve taking time out for regular habits such as taking a nap (in Mediterranean societies), praying or conducting a tea ceremony (as in Japan).

* “Hara hachi bu” – a Confucian teaching that suggests we only eat until we are 80% full.

* Having an “ikigai” – a Japanese word used to define the “reasons for being” and why we get out of bed every morning.
