The regulation of genes is often more interesting than the genes themselves, and it's the environment that regulates genes.

An open mind is a prerequisite to an open heart.

Almost always, genes are about potentials and vulnerabilities rather than about determinism.

The frontal cortex doesn't even fully develop until age 25, which is wild!

Essentially, we humans live well enough and long enough, and are smart enough, to generate all sorts of stressful events purely in our heads.

We all seek out stress. We hate the wrong kinds of stress but when it's the right kind, we love it - we pay good money to be stressed by a scary movie, a roller coaster ride, a challenging puzzle.

We live well enough to have the luxury to get ourselves sick with purely social, psychological stress.
