If a rat is a good model for your emotional life, you're in big trouble.

...when doing science (or perhaps when doing anything at all in a society as judgmental as our own), be very careful and very certain before pronouncing something to be a norm - because at that instant, you have made it supremely difficult to ever again look objectively at an exception to that supposed norm.

But if you get chronically, psychosocially stressed, you're going to compromise your health. So, essentially, we've evolved to be smart enough to make ourselves sick.

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

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

I love science, and it pains me to think that so many are terrified of the subject or feel that choosing science means you cannot also choose compassion, or the arts, or be awed by nature. Science is not meant to cure us of mystery, but to reinvent and reinvigorate it.

We are just another primate but a very confused, malleable one.
