We don't really understand most of what's happening in the cosmos. Is there any afterlife? Who knows.

We're trapped on this very thin slice of perception ... But even at that slice of reality that we call home, we're not seeing most of what's going on.

Because vision appears so effortless, we are like fish challenged to understand water.

If our brains were simple enough to be understood, we wouldn't be smart enough to understand them.

The brain runs its show incognito.

At least 15 percent of human females possess a genetic mutation that gives them an extra (fourth) type of color photoreceptor - and this allows them to discriminate between colors that look identical to the majority of us with a mere three types of color photoreceptors.

Since we live in the heads of those who remember us, we lose control of our lives and become who they want us to be.
