Philosophers, comedians, and tipsy birthday celebrants all have proposed theories about why time seems to move increasingly swiftly as we grow older. But the most disconcerting rationale is not a theory. It is the undeniable realization that every day we live constitutes a smaller percentage of the accrued experience with which we awaken each morning, and therefore seems proportionately a smidgen quicker and smaller than the day before.
