In 1970 Yiannis Karimalis got a death sentence. Doctors in Pennsylvania diagnosed the Greek immigrant with abdominal cancer and told him he'd be dead within a year. He was not yet 40 years old.
Devastated, Karimalis left his job as a bridge painter and returned to his native island of Ikaria. At least there he could be buried among his relatives, he thought—and for a lot less money than in the United States. Thirty-nine years later, Karimalis is still alive and telling his amazing story to anyone who will listen. And when he returned to the States on a recent visit, he discovered he had outlived all the doctors who had predicted his death.
On Ikaria, a mountainous, 99-square-mile island, residents tell this story to illustrate something they've known all their lives: on average, Ikarians outlive just about everyone else in the world.
For three weeks in April, I led a scientific expedition to Ikaria to investigate the reasons for the islanders' remarkable longevity. It was part of my research into the earth's few Blue Zones: places where an extraordinarily high proportion of natives live past 90.
Our team of demographic and medical researchers — funded by AARP and National Geographic — found that an amazing one in three Ikarians reaches 90. (According to the U.S. Census Bureau, only one in nine baby boomers will.)
Most astonishing of all: among the islanders over 90 whom the team studied — about one-third of Ikaria's population who are 90 and older — there was virtually no Alzheimer's disease or other dementia. In the United States more than 40 percent of people over 90 suffer some form of this devastating ailment.
How do we explain these numbers? History tells part of the story.
In antiquity Ikaria was known as a health destination, largely for its radioactive hot springs, which were believed to relieve pain and to cure joint problems and skin ailments.
But for much of the ensuing two millennia, civilization passed over this wind-beaten, harborless island. To elude marauding pirates, Ikarians moved their villages inland, high up on the rocky slopes. Their isolation led to a unique lifestyle.
Over centuries with no outside influences, island natives developed a distinctive outlook on life, including relentless optimism and a propensity for partying, both of which reduce stress.
Ikarians go to bed well after midnight, sleep late, and take daily naps. Based on our interviews, we have reason to believe that most Ikarians over 90 are sexually active.
But what about the Ikarians' culture best explains their long lives?
To find out, we let visitors to our website direct our team's quest. Our online collaborators voted on what we should research next. One day, for example, we interviewed hundred-year-old Ikarians to discover what they'd eaten for most of their lives. The next day we investigated the chemical composition of herbal teas.
In all, we found 13 likely contributors to Ikarian longevity. The formula on the next page may be the closest you'll get to the fountain of youth.
Eat Like an Ikarian
Maintain a Mediterranean diet: Around the world, people who most faithfully stick to a so-called Mediterranean diet — a regimen high in whole grains, fruits, vegetables, olive oil, and fish — outlive people who don't by about six years. The Ikarian version features more potatoes than grains (because they grew better in the mountains) and more meat than fish (because the sea was a day's journey away).
Open the olive oil: Ikaria's consumption of olive oil is among the world's highest. Residents drizzle antioxidant-rich extra-virgin oil over food after cooking, which preserves healthful properties in the oil that heat destroys.
Bake bread: The island's sourdough bread is high in complex carbohydrates and may improve glucose metabolism and stave off diabetes.
Grow your own garden (or find farmers' markets): Fruits and vegetables eaten soon after picking are higher in compounds that decrease the risk of cancer and heart disease.
Enjoy some Greek honey: The local honey contains antibacterial, anticancer and anti-inflammatory properties. (Unfortunately, the health benefits of Ikarian honey do not extend to American honey, as far as we know.)
Graze on greens: More than 150 varieties of wild greens grow on Ikaria. Some have more than ten times the level of antioxidants in red wine.
Sip herbal teas: Steeping wild mint, chamomile, or other herbs in hot water is a lifelong, daily ritual. Many teas lower blood pressure, which decreases the risk of heart disease and dementia.
Live Like an Ikarian
Nap daily: Ikarian villages are ghost towns during the afternoon siesta, and science shows that a regular 30-minute nap decreases the risk of heart attack.
Walk where you're going: Mountainous terrain and a practice of walking for transport mean that every trip out of the house is a mini workout.
Phone a friend: With the island's rugged terrain, family and village support have been key to survival. Strong social connections are proven to lower depression, mortality, and even weight.
Get religion: Ikarians observe Greek Orthodox rituals, and regular attendance at religious services (of any kind ) has been linked to longer life spans.
Throw out your watch: Ikarians don't worry about time. Work gets done when it gets done. This attitude lowers stress, which reduces the risk of everything from arthritis to wrinkles
Do Ikarians possess the true secret to longevity? Well, some combination of their habits is helping them live significantly longer than Americans, who live on average to age 78. We can't guarantee that Ikarian wisdom will help you live to 100. But if Yiannis Karimalis's example is any indicator, it may help you outlive your doctor.
