Every age hath its own problem, and every soul its particular aspiration. The remedy the world needeth in its present-day afflictions can never be the same as that which a subsequent age may require. Be anxiously concerned with the needs of the age ye live in, and centre your deliberations on its exigencies and requirements.
At any rate, that's how I started running. Thirty three""that's how old I was then. Still young enough, though no longer a young man. The age that Jesus Christ died. The age that Scott Fitzgerald started to go downhill. That age may be a kind of crossroads in life.

Life is not stationary. Seconds, minutes, hours, days, weeks, months, and years all tick away at the same clip for everyone. No age-group can be isolated. None of us can settle into infancy, youth, middle age, or old age. We all grow older, and, incidentally, it is an exciting thought if the accent is on growing. "Though our outward man perish," said Paul, "yet the inward man is renewed day by day" (2 Cor. 4:16; italics added).
