If you ever feel lazy or dull, take heart: you're the busiest, brightest thing on the planet.

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.

Our internal life and external actions are steered by biological coctails to which we have neither immediate access nor direct acquaintance.

Love was not specified in the design of your brain; it is merely an endearing algorithm that freeloads on the leftover processing cycles.

When a male vole repeatedly mates with a female, a hormone called vasopressin is released in his brain. The vasopressin binds to receptors in a part of the brain called the nucleus accumbens, and the binding mediates a pleasurable feeling that becomes associated with that female. This locks in the monogamy, which is known as pair-bonding. If you block this hormone, the pair-bonding goes away.
