Is it normal for an adult to be mentally and psychologically stuck as a teen ?
So is it normal for an adult , actually a person in his late twenties to be mentally and psychologically stuck as a teenager , like somewhere between 15 -18 ?, would he be considered retarded ?,since under 18 is still a child , but 18 and above is an adult .
A person with a child mentality is retarded , but is it the same with teen mentality? , and we can take the question further to 30 and 40 something having the mentality of 20 something .
