If you are 29, you are far younger than when you are thirty in terms of numbers psychology.
I also conducted a little experiment on tinder back when the app was in its prime. 26 & 27 was the sweet spot attracting both women in their thirties and 19/ 20 year olds as well. Therefore I will continue to use those ages until I am at least 36 or I can get away with it in looks.
