Even though the outside world has not changed, your brain dynamically presents different interpretations.

There are an infinite number of boring things to do in science.

Awareness of your surroundings occurs only when sensory inputs violate expectations. When the world is successfully predicted away, awareness is not needed because the brain is doing its job well.

Knowing yourself now requires the understanding that the conscious you occupies only a small room in the mansion of the brain, and that it has little control over the reality constructed for you.

In the traditionally taught view of perception, data from the sensorium pours into the brain, works its way up the sensory hierarchy, and makes itself seen, heard, smelled, tasted, felt - "perceived." But a closer examination of the data suggests this is incorrect. The brain is properly thought of as a mostly closed system that runs on its own internally generated activity.

Interestingly, schizophrenics can tickle themselves because of a problem with their timing that does not allow their motor actions and resulting sensations to be correctly sequenced.

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.
