Dutchman Emile Ratelband is on a mission to legally reduce his age from 69 to 49 to boost his profile on the dating application Tinder.
The pensioner wants to be recognised as being 20 years younger than his actual age.
Ratelband argues that he feels two decades younger than he actually is - doctors told him he has the body of a younger man, he says, and while in most cases that compliment is rhetorical, Ratelband is taking a more literal approach.
A court in Arnhem, in the eastern Dutch province of Gelderland, is expected to deliver its decision on Ratelband's age within four weeks.
According to the Dutch newspaper Algemeen Dagblad, or AD, Ratelband told the court he would be happy to delay his pension benefits for 20 years, as a logical extension of his age change. "I agree with you: a lot of years ago we thought that was impossible", he said.
They argued that if Ratelband's age was to be reduced, what would be the status of his early years then?

Justice Ginsburg hospitalized after fracturing ribs in fall
Ginsburg told CNN in July that she thought she had " at least five more years " left before she retired from the Supreme Court. But Ginsburg, the court's oldest sitting justice, has consistently been adamant that she has had no intentions of retiring.
He said: 'When I'm 69, I am limited. If I'm 49, then I can buy a new house, drive a different auto. In Australia, for example, many older people struggle to find work once they reach their 50s and 60s, despite the fact that it is illegal for companies to specifically discriminate against candidates due to their age.
"If I put on Tinder that I am 69, I will not get a response.[As] 49, with that face of mine, then I'm rammed", he said.
Ratelband's argument hinges on transgender people's ability to now change their genders on their birth certificates. "Why not your age?" he told Dutch paper De Telegraaf.
He said employers are reluctant to hire someone as old as a pensioner as a consultant. "Who was that little boy?" he was quoted as saying.
However, he also noted that allowing people to change their birth date would mean legally deleting part of their lives, according to the Telegraph.
It's reported that the court was sceptical of the lawsuit, believing that there was no legal grounds that would allow a person to change their birth date.
