CHENGMAI, China: The elderly residents of one Chinese county have endured invasion, civil war and famine, and many live in unheated concrete shacks on only a few dollars a day.
But they are apparently among the longest-lived people on earth.
Chengmai, a string of villages dotted with orange plantations in the tropical island province of Hainan, claims more than 200 residents aged over 100 out of a population of 560,000 – one of the highest ratios in the world.
They are said to include at least three ‘supercentenarians’ – the name given to those aged over 110 – out of fewer than 400 thought to exist worldwide.
Li Aizhu, whose government-issued residence permit says she was born in 1900, hobbles daily from her tiny concrete bedroom, where an electric fan beats back the intense heat, to watch quacking ducks waddle past her family farmhouse.
“Who are these people?” Li asked relatives when visitors arrived, a shock of white hair framing her wrinkled face.
She aimed the same question at government officials who arrived with a metal plaque declaring her to be a ‘longevity celebrity’, her family said.
It now hangs above a hard wooden bench in her simple living room, entitling her to a 500 yuan (US$81) monthly payment, and free medical treatment.
Other clusters of longevity are said to include Cuba, islands off Greece and Japan, and a peninsula in Costa Rica, with researchers finding common characteristics including an emphasis on family, lifestyles requiring physical activity, and a plant-based diet.
“I’ve never done any exercise, except hard farmwork,” said 86 year-old Wang Kailu, who lives in a simple concrete shack with his wife Wu Aihe.
The couple said they married the day after Japan’s World War Two surrender, 68 years ago.
Experts on ageing who have travelled to the area say several factors could be involved in the phenomenon. Locals, though, claimed a healthy reliance on alcohol was vital.
Xu Yuhe, whose residency permit lists her as 104, told AFP that she takes daily shots of ‘Three Coconut Spring’ a local grain spirit.
“I drink alcohol every evening, just a little bit, it helps you feel warm,” added Sheng She, an 80-year-old who says she has 31 children and grandchildren.
Experts say an active social life is also a key to longevity, and each morning dozens of Chengmai’s elderly pack out benches in a teahouse, with men at the back playing cards and women at the front, chatting and listening to clattering opera recordings.
“I come here every morning to exercise, watch opera and drink tea,” said Sheng, before darting out to test her strength on a yellow-painted metal exercise machine.
Experts say longevity zones around the world are rarely in rich areas.
“If you’re living in a climate like that you don’t need very much to be comfortable: simple housing, a mosquito net, some rattan chairs and other people to hang out with,” said Holdaway. “It’s a different matter if you live in the North where you have to spend a lot of time indoors and fresh food is expensive in the winter.”
Li Aizhu, though, has a simpler explanation. “We asked her once,” said the 113-year-old’s great-granddaughter, Yi Mei. “She said its because she eats a lot of peanut oil, that’s her secret.” — AFP
