Why do some people live longer than others?

Prioritize your happiness
Feeling happy can significantly increase your longevity.In fact, happier individuals had a 3.7% reduction in early death over a 5-year study period.A study of 180 Catholic nuns analyzed their self-reported levels of happiness when they first entered the monastery and later compared these levels to their longevity.Those who felt happiest at 22 years of age were 2.5 times more likely to still be alive six decades later.Finally, a review of 35 studies showed that happy people may live up to 18% longer than their less happy counterparts .
