How Old Are You?
Most people seem to think being young is some sort of idyllic age and growing old is some sort of curse to be avoided. The fact is you are young as long as you are planning for tomorrow. You are over the hill as soon as you stop planning for tomorrow and try to live on your yesterdays.
Planning for tomorrow means you realize you still have work to do. Your bones may creak a bit as you bend them. Your muscles may need a third or fourth command before they really get into action. But your mind can be far more alert and active at 75 than it was at 35. Your experience is vast. You know what won't work and save yourself a lot of wasted steps. Your body may be bent with age but your mind, your imagination, your memory can be functioning in their prime. When someone asks your age, tell him you are young enough to have a lifetime of plans yet to be fulfilled, an unending supply of tomorrows still to be lived.
