Dopamine @ Works

"Humans have that second relentless cognitive clock ticking inside their heads, counting down in a covert yet unassailably certain way the hours and minutes of our remaining time on Earth. Just as we literally hunger for food and water to forestall physiological death, we figuratively hunger for wisdom to forestall spiritual and existential death. The path of the well-lived, virtuous life has meaning precisely because that path arrives, for every living soul, by whatever circuitous route, at exactly the same destination."
