imagine that you spent your whole life at a single house.each day at the same hour you entered an artificially-lit room,undressed and took up the same position in front of a motion picture camera.it photographed one frame of you per day,every day of your life. on your seventy-second birthday,the reel of film was shown.you saw yourself growing and aging over seventy-two years in less than half an hour (27.4 minites at sixteen frames per second). images of this sort ,though terrifying, are helpful in suggesting
1 but useful perspectives of time. they may ,for example ,
2 the telescoped ,almost
3 charater of the past as seen through the eyes of an anxious or disa-ffected individual. or they may suggest the
4 brevity of our lifes in the cosmic scale of time. if the estimated age of the
5 were shorted to seventy-two years, a human life would take about ten seconds.
but look at time the other way. each day is a
6 7 of over 86000 seconds. during each second, the number of distinct
8 functions going on with the human body is comparable to the mumber of seconds in the estimated age of the cosmos. a few seconds are long enough for a revolutionary idea, a startling communication, a baby's conception, a wounding insult, a sudden death. depending on how we think of them, our lives can be
9 long or infinitely short.
