The motivational speaker and self-help guru says he is discriminated against because of his age, and if transgender people can legally change their sex then he should be able to change his birth date.

The local authority has refused his request and the case has now gone to court.

"I have done a check-up and what does it show? My biological age is 45 years," he says.

"When I'm on Tinder and it says I'm 69, I don't get an answer. When I'm 49, with the face I have, I will be in a luxurious position.

"Transgender people can now have their gender changed on their birth certificate, and in the same spirit there should be room for an age change."
