Cognitive Dissonance

Maybe not in the precise psychological sense, but cognitive discord of some sort is what I experienced tonight when I went from reading this in-depth analysis of peak oil* to this celebration of the pursuit of bodily near-immortality here on earth.

*Sample conclusion:

Within a few decades, the U.S. will lack automobile, truck, air, and rail transportation, as well as mechanized agriculture, adequate food and water supplies, electric power, sanitation, home heating, hospital care, and government services.

UPDATE: I'm reminded of the joke a classmate of mine made about Hobbes' description of the state of nature, in which life was "solitary, poor, nasty, brutish, and short": "What, would you want life to be solitary, poor, nasty, brutish, and long?"
