Youth, like sand, slips away, one grain at a time through your fingers. It might appear as if nothing were changing, but one day, when you approach your fourth decade, you will feel that last grain escape between them. And all that will be left are the dry imprints age has left in your palm. Your hands begin to feel distant and clumsy, your thoughts, faint. Your ankles and knees remind you not to continue leaping up the stairwell and your memory fails to remind you why you scaled them in the first place. But there is nothing to fear good friend. It is merely a reminder to put what is left of your time to good use. You may have still another three decades of good health and strength. So carry on. Your best work is yet to come, for a bare hand is an able one.
