Dear Friends: The passage of time is constant. It
is determined by the physical characteristics of our universe.
Everything we do has a time limit. Time
is also expressed as speed. Thus,
we talk about the speed of sound and breaking the sound barrier by aircraft that
travel faster than the speed of sound. Seated
in the Concord over the Atlantic, you notice that the cabin is silent because of
traveling faster than the speed of sound. You
get to New York at an earlier hour than when you left London, yet three hours of
time have passed. Thus, the trip
did not gain time, even though the clock suggested otherwise.
When you cross the International Dateline by traveling east, you don’t
really gain a day. Time has passed,
but was it fun? Time can seem to slow down, when you are not having fun.
Remember the dental chair and waiting for news about surgery on your
spouse, or your child. When you are having fun, time flies. So time is constant. Time
flies whether you are having fun or not. Time
doesn’t care. You should cherish
the time you have and plan to have fun for as much time as you have left. Your friend,
