Nature vs Nurture
A healthy lifestyle can take you only so far. Research shows that eating right, exercising often, and otherwise adopting healthy habits can extend the lifespan—to about 80, or even 90 years of age. After that, genetics are likely the most significant factor. Do you have any centenarians in your family? Read the NYT article to find out more about longevity influences.

Centenarian In Chief
Former President Jimmy Carter, who died on December 29th, was 100 years old–a milestone age not achieved by just anyone. To look at the lynchpins of his long and active life, Fortune spotlights Carter’s three strategies for longevity. Read on to see how fitness, love, and community factored in.

Can Do at 102
We recently had the privilege of visiting Rancho La Puerta in Baja California, MX, and attended a Q&A with its 102-year-old founder, Deborah Szekely. What an amazing life she’s led, from founding the wellness retreat and spa in 1940, to establishing San Diego’s New Americans Museum and Immigration Learning Center at age 80. Her advice for staying healthy and engaged? Maintain an active social network, be positive, and just move (she still walks one mile every day)! Read more about Deborah’s remarkable story in this Fortune interview.

The Long and Winding Road
Might we take a different route if we knew we’d live to be 100? According to the Pew Research Center, nearly half a million Americans are expected to live to at least 100 years of age by 2050—that’s quadruple the current number of centenarians. Laura Carstensen, founder of Stanford University’s Center on Longevity, suggests we need to rethink our traditional pathways to optimize this new-found longevity. For example, she suggests making childhood longer, or working less while rearing children and more later in life instead of retiring. Read on for more innovative ideas.

Pragmatism + Optimism = 102 and Still Going Strong
Meet Hilda Jaffe, 102, who defies age and is the veritable embodiment of a ‘superager.’ As the Washington Post reports, at age 88, Jaffe decided to turn the page and start a new chapter, selling her home in New Jersey and moving to Manhattan, taking up residence in the Hell’s Kitchen neighborhood. More than a decade later, she is still actively enjoying the easy walks to grocery stores, seeing opera, and living independently in the city that never sleeps. According to Sofiya Milman, director of human longevity studies at the Institute for Aging Research at Albert Einstein College of Medicine, superagers typically have a very positive outlook on life, with built-in resilience. Read on to learn more about Jaffe’s approach to life and what studies of other superagers reveal.
