39 by Henry Lawson — Read

I only woke this morning / To find the world is fair -- / I'm going on for forty, / With scarcely one grey hair; / I'm going on for forty, / Where man's strong life begins, / With scarce a sign of crows' feet, / In spite of all my sins.

Then here's the living Forties! / The Forties! The Forties! / Then here's the living Forties! / We're good for ten years more.
