Living to be over a century old is a big personal success. You've proven that you can survive with genetics and history against you - and you even get a letter from the Queen.
However, we'd assume living long enough to become a centenarian could get pretty lonely, so how great would it be to share the experience with your twin sibling?

A pair of Britain's oldest twins, living in Stourport-on Severn, Worcestershire, celebrated their 101st birthday with a party yesterday, complete with two massive birthday cakes.
But Irene Crump and Phyllis Jones's cakes were so full of flaming candles that Phyllis' son Carl, needed to use a wet cloth to put them out. Imagine getting to the age where your own birthday is a fucking fire hazard... Ultimate life goals, right there.
"I think I will be scared to add the extra candle next year!" Carl said. "They both found it very funny - they had a good chuckle.
"You could always say they have been risk takers, my mum [Phyllis] more so than Irene, as she was a keen gardener and would cut down trees herself."
Phyllis and Irene were born 25 minutes apart in 1916, midway through the First World War. They went to the same school and worked the same first job.
The pair are so close that they have each other's first names for their middle names, and have been living together again for the past eight years.
"They have their ups and downs and their little arguments like anyone but obviously they love each other very much," Carl added.
"They're totally different though - Auntie Rene, as I call her, has always been very methodical and careful but my mum just races around doing things."

The twins worked the first same first job at Steatite Porcelain Products before the younger Irene married the farmer Samuel Crump and became a farmer herself.
Samuel lived into his 90s himself and died in 1999, while Phyllis' husband, Ray Jones died at the grand old age of 91 in 2006.
A few years after Ray died, the pair decided to move back in together, despite only ever having lived a few miles apart. Now that's inseparable.
"Hard work and good food is our secret, that's all I can put it down to," Irene said.
"We have had a good life, we've never needed to ask for anything and even now we only have to talk to Carl and his wife - and they are golden to us."
The bond the twins share is enough to make you want to see the other side of 100 yourself. Along with the big cake, of course.
