Time Waits For No Man

Time waits for no man. Or so they say. Presumably, it waits for no woman either. And anyway, how do they know? Have they interrogated time? Have they asked it to keep a diary of its movements? Have they followed it around with a stopwatch to see what it does each day? We think we know a lot about time, but actually, we know very little. Sometimes it seems as if time may have just been waiting after all.
