As a favor to some friends and former colleagues in the UK, I recently inspected a few rock samples. Geology isn't normally my forte, but as I handled the samples (from some of Earth's oldest deposits) I was struck by their staggering age. Not to sound too morbid or pseudo-philosophical, but in emphasising the ephemeral nature of life they reminded me of Lincoln's words: this too shall pass. It's comforting, sometimes, to be reminded that nothing is really forever.
