The deep secret of the brain is that not only the spinal cord but the entire central nervous system works this way: internally generated activity is modulated by sensory input. In this view, the difference between being awake and being asleep is merely that the data coming in from the eyes anchors the perception.

Given the billions of neurons, this means there are as many connections in a single cubic centimeter of brain tissue as there are stars in the Milky Way galaxy.

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.

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.

Humans have discovered that they cannot stop Death, but at least they can spit in his drink.

We open our eyes and we think we're seeing the whole world out there. But what has become clear—and really just in the last few centuries—is that when you look at the electro-magnetic spectrum we are seeing less than 1/10 Billionth of the information that's riding on there. So we call that visible light. But everything else passing through our bodies is completely invisible to us. Even though we accept the reality that's presented to us, we're really only seeing a little window of what's happening.

We are not at the center of ourselves, but instead - like the Earth in the Milky Way, and the Milky Way in the universe - far out on a distant edge, hearing little of what is transpiring.
