Two sisters from mid Wales have the perfect answer to French twins of 98 claimed to be the world's oldest.
Although Raymonde and Lucienne Wattelade are officially recognised by Guinness World Records, Ena Pugh and Lily Millward, from Powys, are 100.
Mrs Millward's daughter said the French pair were "mere youngsters" compared to her mother and aunt.
The farmer's daughters' family are set to contact Guinness World Records about the title.
The Welsh twins were born on 4 January, 1910, when Queen Victoria's son Edward VII was king.
Mrs Millward said their secret to a long life was "having a joke with each other".
Mrs Pugh, from near Builth Wells, and Mrs Millward, from near Brecon, meet for weekly shopping sessions in Brecon, and chat on the telephone virtually every night.
Great-grandmother Mrs Millward said: "We used to work on the farm all day, but we would enjoy ourselves.
"It was a lot of fun and sociable. We've been very lucky and we have always had good health."
Mrs Pugh said a lot of life was down to luck.
She added: "But I think being kind, good and helping others is the main thing.
"We've had a very happy life and enjoy seeing each other."
Their family had no idea they could be the oldest in the world until twins in France claimed the record last week.
Raymonde and Lucienne Wattelade, who are officially recognised by Guinness World Records, live in Saint-Georges-de-Didonne, south-western France.
Mrs Millward's daughter Dianne Powell, 64, said: "The French sisters were mere youngsters compared to my mother and aunt.
"As twins they have been very close all their lives and they are still very close now.
"Each of them jumps on a bus on their own every Friday so they can go shopping together and have a chat over a cup of tea.
"And they ring each other almost every evening although they are both very hard of hearing - they can't really always know what the other is saying but just enjoy talking to each other."
Mrs Pugh was born first on 4 January, 1910 with Lily a few minutes later in their family farm cottage in the village of Garthbrengy, near Brecon.
Mrs Pugh still lives in her country cottage where she raised their three children, and now has 10 grandchildren and three great-grandchildren.
Mrs Millward lives in a smallholding and has two children, five grand-children and nine-great grandchildren.
Both of the twins shun some of the luxuries of modern life, and neither has central heating.
Mrs Powell said: "They are both still very active - my mother has just made a load of jam and chutney for the local show.
"My mother was still doing aerobics until six months ago, but had to give it up because she said some other old people needed it more than her."
