Of Men And... Not So Much

I have recently tested a hypothesis of mine according to which men of all ages never  manage to overcome the mental age of 14. I tested on male subjects aged 18 to 80. The result of the study was that most of them don't even reach mental puberty and that the vast majority places itself in the 3rd grade, as they do have some basic numeracy skills, essential to playing video games and some geolocating skills, meaning that they can find their own way home with or without the use of a GPS. The extremely few ones who manage to reach the mental age of 18 are mostly victims of their own success, as being entitled to alcohol consumption, they often regress to the stage of toddlers.
