“Our brains are seventy-year clocks… Tic-tac! tic-tac! go the wheels of our thought; our will cannot stop them; they cannot stop themselves; sleep cannot still them; madness only makes them go faster; death alone can break into the case, and, seizing the ever-swinging pendulum, which we call the heart, silence at last the clicking of the terrible escapement we have carried so long beneath our wrinkled foreheads.”

-Oliver Wendell Holmes
