A long time ago, probably after reading Holden Caulfield's ruminations about where Central Park's ducks go in the winter, I wondered about what fish do in ponds and lakes when the water freezes.
What I learned is that fish can lower their metabolism. They "slow down" in effect, lower their pulse, so they can survive adverse conditions.
I've always envied this ability in fish.
I wish when I was stuck on a long plane flight, in shul during the High Holy Days, or, most often, trapped in some endless and mindless morass at work--the usual messy stew of indecision and pontification--I was more like a fish.
I wish I could lower my metabolism until it all just goes away.
