It must be to do with London's water !
What else could it be ??
A London pensioner has become one of the world's oldest fathers - at the grand old age of 75.
Paul-Louis Mariasusay was delighted that his new bride has presented him with a baby son, just months after they married.
The veteran dad already has two daughters, one of whom is older than his new 38-year-old wife Gena, and five grandchildren.
He said: "I may be a pensioner, and it is almost 40 years since I looked after a baby, but I haven't forgotten how to change a nappy and it is just marvellous to be a father again.
"The baby came as a complete surprise. I had no idea that I could still become a father at my age but Xavier is a lovely gift."
"I get plenty of comments about Xavier when I'm pushing him in his pram from people who think I am his granddad. I am proud of Gena and Xavier and I want to walk with my head up high."
How sure the man that he is the father of that 1? jejeje Lol
Definitely the water.. Perhaps the odd viagra also..
