According to dobbs, what purpose do the changes in the teenage brain serve? why are they "adaptive" (useful for humans as a species)?

Rewiring, sort of an ¨upgrade¨ or maturing.

They are adaptive to prepare for their next phase of evolution, the consideration of leaving home.

Explanation:

According to the researcher David Dobbs, the purpose of the massive changes that are undergone by teenage brains is with the purpose of maturing the brain within itself to face possible upcoming changes.

The process of being ¨adaptive¨ is called as such due to the fact that during this period of time, the teenage brain undergoes a ¨rewiring¨ in order to prepare for a time when the individual must face changes such as leaving the comfort zone of home and face more daring challenges like coping with daily decisions and tasks outside in the world, as well as socializing with others.

i’m writing a memoir and i’ve been given the great suggestion of placing a ‘sub-narrative’ within some of the chapters – sort of, what was going on with me in the grand scheme of things.

i was wondering how to format this so that it is very obvious we are stepping out the of story.

firstly is a change in font from serif to sans workable? i also use dashes for a scene change. was thinking of using a different scene-changer too.

here’s a (shortened) example:

university – or what’s known as ‘uni’ in australia – were some of the best days of my life. where else do you get to potter around in a great location, have very little responsibility, learn lots of things, do lots of things and walk out four years later with a bonus – a degree!

with my university years i had immersed myself into community of intelligent ambitious people. generally everyone had a confidence about themselves. they knew where they were going in life and weren’t threatened by others.
