Old Age

I used to think that growing old was reckoned just in years,
But who can name the very date when weariness appears?
I find no stated time when man, obedient to a law,
Must settle in an easy chair and from the world withdraw.
Old Age is rather curious, or so it seems to me.
I know old men at forty and young men at seventy-three.

I'm done with counting life by years or temples turning gray.
No man is old who wakes with joy to greet another day.
What if the body cannot dance with youth's elastic spring?
There's many a vibrant interest to which the mind can cling.
'Tis in the spirit Age must dwell, or this would never be:
I know old men at forty and young men at seventy-three.

So much to do, so much to learn, so much in which to share!
With twinkling eyes and minds alert some brave both time and care.
And this I've learned from other men, that only they are old
Who think with something that has passed the tale of life is told.
For Age is not alone of time, or we should never see
Men old and bent at forty and men young at seventy-three.
