The brain runs its show incognito.

The first lesson about trusting your senses is: don't. Just because you believe something to be true, just because you know it's true, that doesn't mean it is true.

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

We believe we're seeing the world just fine until it's called to our attention that we're not.

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

All activity in the brain is driven by other activity in the brain, in a vastly complex, interconnected network.

When people fall in love, there´s period of up to three years during which the zeal and infatuation ride at a peak. The internal signals in the body and breain are literally a love drug. And then it beginds to decline. From this perspective, we are preprogramed to lose interest in a sexual partner after the time required to raise a child has passed - which is, on average, about 4 years.
