A former pub landlady toasted her 100th birthday with family and friends this week - and then revealed the secret to her longevity is a drop of whisky.

Trudy Raven ran The Bell in Cawston, with her late husband James, just a few doors from her current home, where she has stayed for the past 34 years.

She revealed each customer had their own special mug when she was in charge but trade suffered when drink driving laws were introduced in 1966.

When asked the secret to a long and happy life, Trudy, who is believed to be the oldest resident in the village, said: 'Hard work, good living, never smoking; and a touch of whisky.'

The centenarian, who has two sons, six grandchildren and 13 great grandchildren, was thrown a surprise party by family on Sunday to mark the milestone ahead of a private celebration on her official birthday on Tuesday.

Her earliest memories included getting an open-top tram to work at a shoe factory in Norwich at the age of 14.

Trudy, who still enjoys gardening at her home, said: 'Life has been very good. I loved going to school, the teachers were wonderful and there were 48 pupils to a class in those days. There was no unrest, everybody helped each other.'

But she added: 'Life has changed dramatically. Youngsters these days have so much where we didn't. I never see them looking at the price of anything. We had to make our own clothes, everything was done yourself.'
