Not even identical twins can have the exact same experiences, and their brains are not wired the same way.

Years of research show us that the less control a person feels over an aversive stimuli coming at them, the more likely they are to disengage. Complete loss of control over a sustained period of time can actually lead to depression. It then follows that giving the person a level of control over the situation reduce the stress - and perhaps restore the disengagement.

What you do and learn in life physically changes what your brain looks like—it literally rewires it.

A factory worker at an assembly line, who can learn their job in 5 minutes, can get bored fairly easily, and disengage completely.

Though we have been stuffing them into classrooms and cubicles for decades, our brains actually were built to survive in jungles and grasslands. A lifetime of exercise can result in a sometimes astonishing elevation in cognitive performance, compared with those who are sedentary.

What's obvious to you is obvious to you.

Change often involves loss, so change can be a risky experience.
