Hundreds of birthday candles were purchased in Lunenburg this year, as more than a handful of its residents aged into the triple digits.

The centenarians are mostly women, and the fact they've all lived past 100 has the local medical community baffled.

Statistics show that there are 50 centenarians for every 100,000 people in Lunenburg, compared to a ratio of three for the same number in other parts of the world.

Diet could be the key, says geriatrician Chris MacKnight.

"Fish diet maybe? Physical activity? A lot of centenarians we talk to talk about this salt air as being the secret but I have my doubts about that one, but you never know," he said, adding that genes may also be a factor.

"The people in Lunenburg are largely descended from a small group of German settlers," MacKnight said.

"There's an Acadian population in Yarmouth that's largely descended from a small group of Acadian settlers so you would wonder if there's a gene in those families that promoted a long and healthy life."

One woman, Elizabeth Slauenwhite enjoys her 100 years, but admits, "it feels not as good as when you're 16, but it's not bad. 'course I've got all my faculties. That helps."

Another woman from nearby Mahone Bay, 103-year-old Ella Hintz, stays sharp by taking her motorcycle on long trips.

The longevity stands in contrast with provincial studies that show Nova Scotians lead unhealthy lifestyles, are inactive and overweight.

Centenarian Vera Baker has her own theory about living so long: "I just took care of myself. I didn't drink nor smoke. Oh yes, and prayer, but not too much prayer."

"I don't wish to be 200. I just go as the Lord wants me," she added.
