Question

There is a famous collection of movies about a trio of kids who are in the same "year" at school. You may have heard of them, but just in case you haven't, they are the Harry Potter films. Of the three characters, Hermione is very level-headed, dislikes breaking the rules, and always tries to act responsibly. Ronald, on the other hand, tends to be a bit of a slacker, is irresponsible, and is often more interested in having fun than he is taking care of his obligations. Hermione's ____ age appears to be much higher than Ron's.

Answer 1

The answer is: mental age

The way we measure age is generally divided into two, Chronological and mental age.

Chronological age is measured by counting how much years have passed since our birth, mental age on the other hand is measured by the combination of our personality.

People in higher mental age tend to be really more responsible about their well being and would think about the consequences before taking any action ( Just like Hermione)
