Longevity

The horse and mule live thirty years
And never know of wines or beers.
The goat and sheep at twenty die
And never taste of scotch or rye.
The cow drinks water by the ton
And at eighteen is mostly done.
The dog at fifteen cashes in
Without the aid of rum or gin.
The cat in milk or water soaks
Then at twelve it drops and croaks.
The modest, sober, bone-dry hen
Lays eggs for nogs, and dies at ten.
All animals are strictly dry,
They sinless  live and sinless die.
But sinful, ginful, rum-soaked men
Survive for three-score years and ten.
