How to live to 100

Worldwide, life expectancy is higher than ever before. In fact, a United Nations report shows that 20% of the population will be aged 65 years and older by 2050 — a figure which is likely to continue rising.

But although the odds are increasingly in our favor, we continue to turn to centenarians for advice. Based on analyzing 100 interviews with people aged 100 or above, here are their secrets for a long, happy and healthy life.

Our genetic makeup and lifestyle habits influence longevity, but the impact each element plays is a hotly-debated topic. The current ratio suggests that genetic risk factors control 25% and lifestyle risk factors control 75%, but this ratio fluctuates in line with new research on factors reported to reduce risks to morbidity and mortality. Regardless of the precise weighting of this ratio, it’s clear that a long life boils down to far more than simply smart genes and dumb luck.

Although eating healthily has a strong showing in second place, even more centenarians attributed their long lifespans to less conventional advice involving daily treats such as chocolate, bacon or sugary drinks.

Elizabeth Sullivan, 104, sums up this paradox perfectly in a conversation with her doctor:

“I saw the doctor and he said, ‘Are you careful about what you eat?’ and I said, ‘Certainly not, I drink three Dr Peppers a day,’ and he said, ‘Oh my goodness, that’s too much sugar. You will die if you keep drinking that,’” she recounted. “But 10 years later he died and I had to change doctors. So I’m still drinking three Dr Peppers a day and people said that’s bad for me but you know, not very many people live to be 104. So I guess the sugar in the Dr Peppers have kept me alive all this time.”

Somewhat controversially, more centenarians recommended a daily tipple than abstaining from drinking alcohol entirely — seemingly claiming that a little bit of the bad stuff might do us some good after all.

Other popular advice included staying active, keeping a positive attitude, and maintaining relationships with family and friends. Similarly, getting enough sleep, being nice to others, and having religious faith were also acknowledged as important parts of living well into old age.

Judging from the advice collated, striking a happy balance seems to be key to a long and healthy life. None of the centenarians featured in the research recommended crash diets or complete lifestyle overhauls. Instead, their tips were tailored to their own lifestyles and practiced consistently. That could mean indulging in a daily glass of wine, eating plenty of vegetables, or simply basking in the warmth of a loving network of family and friends.
