Like The Dude said, this is an effort by your friends at peakoil.com to prepare you for the future; hours gazing as each drop from your solar still collects in the ancient Big Gulp cup, countless hours waiting at the trip wire to your deadfall willing your stomach to stay quiet, endless time hiding in a dead moose carcass as the zombies steal a summer's worth of collected acorns.
You don't have to thank us.
