Living Long and Prospering on Ikaria

It’s safe to suggest that most of us above a certain age — let’s say 30 — wish to stay young. It is also safer to suggest, in the absence of a solution to this first wish, that many of us wish to age gracefully and happily. Yet for most of us, especially in the West, we age in a less dignified manner in combination with colorful medicines, lengthy tubes, and unpronounceable procedures. We are collectively living longer. But, the quality of those extra years leaves much to be desired.

In a quest to understand the process of aging more thoroughly researchers regularly descend on areas the world over that are known to have higher than average populations of healthy older people. These have become known as “Blue Zones”. One such place is a small, idyllic (there’s a clue right there) Greek island called Ikaria.

From the Guardian:

Gregoris Tsahas has smoked a packet of cigarettes every day for 70 years. High up in the hills of Ikaria, in his favourite cafe, he draws on what must be around his half-millionth fag. I tell him smoking is bad for the health and he gives me an indulgent smile, which suggests he’s heard the line before. He’s 100 years old and, aside from appendicitis, has never known a day of illness in his life.

Tsahas has short-cropped white hair, a robustly handsome face and a bone-crushing handshake. He says he drinks two glasses of red wine a day, but on closer interrogation he concedes that, like many other drinkers, he has underestimated his consumption by a couple of glasses.

The secret of a good marriage, he says, is never to return drunk to your wife. He’s been married for 60 years. “I’d like another wife,” he says. “Ideally one about 55.”

Tsahas is known at the cafe as a bit of a gossip and a joker. He goes there twice a day. It’s a 1km walk from his house over uneven, sloping terrain. That’s four hilly kilometres a day. Not many people half his age manage that far in Britain.

In Ikaria, a Greek island in the far east of the Mediterranean, about 30 miles from the Turkish coast, characters such as Gregoris Tsahas are not exceptional. With its beautiful coves, rocky cliffs, steep valleys and broken canopy of scrub and olive groves, Ikaria looks similar to any number of other Greek islands. But there is one vital difference: people here live much longer than the population on other islands and on the mainland. In fact, people here live on average 10 years longer than those in the rest of Europe and America – around one in three Ikarians lives into their 90s. Not only that, but they also have much lower rates of cancer and heart disease, suffer significantly less depression and dementia, maintain a sex life into old age and remain physically active deep into their 90s. What is the secret of Ikaria? What do its inhabitants know that the rest of us don’t?

The island is named after Icarus, the young man in Greek mythology who flew too close to the sun and plunged into the sea, according to legend, close to Ikaria. Thoughts of plunging into the sea are very much in my mind as the propeller plane from Athens comes in to land. There is a fierce wind blowing – the island is renowned for its wind – and the aircraft appears to stall as it turns to make its final descent, tipping this way and that until, at the last moment, the pilot takes off upwards and returns to Athens. Nor are there any ferries, owing to a strike. “They’re always on strike,” an Athenian back at the airport tells me.

Stranded in Athens for the night, I discover that a fellow thwarted passenger is Dan Buettner, author of a book called The Blue Zones, which details the five small areas in the world where the population outlive the American and western European average by around a decade: Okinawa in Japan, Sardinia, the Nicoya peninsula in Costa Rica, Loma Linda in California and Ikaria.

Tall and athletic, 52-year-old Buettner, who used to be a long-distance cyclist, looks a picture of well-preserved youth. He is a fellow with National Geographic magazine and became interested in longevity while researching Okinawa’s aged population. He tells me there are several other passengers on the plane who are interested in Ikaria’s exceptional demographics. “It would have been ironic, don’t you think,” he notes drily, “if a group of people looking for the secret of longevity crashed into the sea and died.”

Chatting to locals on the plane the following day, I learn that several have relations who are centenarians. One woman says her aunt is 111. The problem for demographers with such claims is that they are often very difficult to stand up. Going back to Methuselah, history is studded with exaggerations of age. In the last century, longevity became yet another battleground in the cold war. The Soviet authorities let it be known that people in the Caucasus were living deep into their hundreds. But subsequent studies have shown these claims lacked evidential foundation.

Since then, various societies and populations have reported advanced ageing, but few are able to supply convincing proof. “I don’t believe Korea or China,” Buettner says. “I don’t believe the Hunza Valley in Pakistan. None of those places has good birth certificates.”

However, Ikaria does. It has also been the subject of a number of scientific studies. Aside from the demographic surveys that Buettner helped organise, there was also the University of Athens’ Ikaria Study. One of its members, Dr Christina Chrysohoou, a cardiologist at the university’s medical school, found that the Ikarian diet featured a lot of beans and not much meat or refined sugar. The locals also feast on locally grown and wild greens, some of which contain 10 times more antioxidants than are found in red wine, as well as potatoes and goat’s milk.

Chrysohoou thinks the food is distinct from that eaten on other Greek islands with lower life expectancy. “Ikarians’ diet may have some differences from other islands’ diets,” she says. “The Ikarians drink a lot of herb tea and small quantities of coffee; daily calorie consumption is not high. Ikaria is still an isolated island, without tourists, which means that, especially in the villages in the north, where the highest longevity rates have been recorded, life is largely unaffected by the westernised way of living.”

But she also refers to research that suggests the Ikarian habit of taking afternoon naps may help extend life. One extensive study of Greek adults showed that regular napping reduced the risk of heart disease by almost 40%. What’s more, Chrysohoou’s preliminary studies revealed that 80% of Ikarian males between the ages of 65 and 100 were still having sex. And, of those, a quarter did so with “good duration” and “achievement”. “We found that most males between 65 and 88 reported sexual activity, but after the age of 90, very few continued to have sex.”
