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.

Some men keep all their friendships warm,
and welcome friendships new,
They have no time to sit and mourn the things they used to do.
This changing world they greet with joy and never bow to late;
On every fresh adventure they set out with hearts elate
From chilling fear and bitter dread they keep their spirits free
While some seem old at forty they stay young at seventy-three.
