A healthy dose of sunshine may be the secret to staying young, British scientists have disclosed.

Vitamin D is produced naturally by the skin in response to sunlight and may help to slow the ageing process and protect against heart disease, according to the study.

Researchers from King's College London studied 2,160 women aged between 18 and 79, looking at their telomeres - a biological marker of ageing found in DNA．As people get older, their telomeres get shorter and they are easy to have illnesses.

But the study found women with high levels of vitamin D had comparatively longer telomeres - a sign of being biologically younger and healthier.

The study suggests vitamin D may help to slow down the ageing process of DNA, and therefore the ageing process as a whole.

Lead researcher Dr Brent Richards said: "These results are exciting because they prove for the first time that people who have higher levels of vitamin D may age more slowly than people with lower levels of vitamin D．

"This could help to explain how vitamin D has a protective effect on many ageing related diseases, such as heart disease and cancer."

He said further studies are required to confirm the findings.

Professor Tim Spector, head of KCL's twin research unit, and a co-author of the report, added: "Although it might sound absurd(荒谬的), it's possible that the same sunshine which may increase our risk of skin cancer may also have a healthy effect on the general ageing process."

Vitamin D made by the action of sunlight on the skin accounts for 90 per cent of the body's supply, but lower levels can also be obtained through food such as fish, eggs and breakfast cereals.

Other studies have suggested the vitamin plays a key role in protecting against cancer and heart disease.

Several times my daughter had telephoned to say, “Mother, you must come to see the daffodils (黄水仙) before they are over，” I wanted to go, but it was a two－hour drive from Laguna to Lake Arrowhead. “I will come next Tuesday，” I promised, a little reluctantly, on her third call.

Next Tuesday dawned cold and rainy. Still, I had promised, and so I drove there. When I finally walked into Carolyn's house and hugged and greeted my grandchildren. I said. “Forget the daffodils, Carolyn! The road is invisible in the clouds and fog, and there is nothing in the world except you and these children that I want to see！”

My daughter smiled calmly and said. “We drive in this all the time, mother. You will never forgive yourself if you miss this experience.”

After about twenty minutes, we turned onto a small gravel road and I saw a small church. On the far side of the church, I saw a hand－lettered sign that read: “Daffodil Garden.”

We got out of the car and each took a child's hand. And I followed Carolyn down the path. Then, as we turned a corner of the path. and I looked up and gasped.Before me lay the most glorious sight. There were five acres of flowers. “But who has done this？” I asked Carolyn. “It's just one woman，” Carolyn answered. “That's her home.” Carolyn pointed to a well－kept A－frame house that looked small and modest in the midst of all that glory. We walked up to the house. On the patio(露台), we saw a poster. “Answers to the Questions I Know You Are Asking” was the headline.

The first answer was a simple one. “50,000 bulbs(球茎)，” it read. The second answer was, “One at a time, by one woman.” The third answer was, “Began in 1958.”

I thought of this woman whom I had never met, who, more than forty years before, had begun—one bulb at a time—to bring the beauty and joy to the mountain top.
