He says he doesn't want to simply change his age on his profile, because "if you lie, you have to remember everything you say".
The judge conceded that the ability to change gender was a development in the law. "Why can't I decide my own age?" he said, missing some points.
The life coach, who specialises in "self-awareness" training, said he felt discriminated against because of his advanced years, adding that while he does not need dating apps, the custom of giving his age to a prospective lover was cramping his style. "Nowhere are you so discriminated against as with your age".
The man is requesting that his birthday change from March 11, 1949 to March 11, 1969.
Ratelband said there are a number of reasons behind his wish to be younger, ranging from improvements in his love life to saving the government almost $350,000 by renouncing his pension. He also argued that according to his doctors, he has the body of a 45-year-old. He says that with his youthful face and an age of 49, he would get more dates, possibly with younger women.
Ratelband thinks his actual, real current age is limiting, especially when it comes to trying to find a date online.
He said: "In my mind I was never allowed to be a little girl so I'm filling that tank of little girl experiences". By changing your age you would be getting rid of 20 years of data on someone and essentially erase real events that took place in those years.
Ratelband, a media personality and motivational guru specializing in self-awareness, compares his attempt to turn back the clock to identifying as transgender.
He also argues that his wish would be good for the government, as he will renounce all his pension benefits until he reaches retirement age again.
He is expected to receive a verdict in the next four weeks.
One of the judges was quoted as saying: "Who were your parents looking after then (referring to the 20 years Ratelband wants to erase)?"
