Nothing so foreign but th' athletic hind
Can labour into blood. The hungry meal
Alone he fears, or aliments too thin;
By violent powers too easily subdued,
Too soon expelled. His daily labour thaws,
To friendly chyle, the most rebellious mass
That salt can harden, or the smoke of years;
Nor does his gorge the luscious bacon rue,
Nor that which Cestria sends, tenacious paste
Of solid milk.* But ye of softer clay,
Infirm and delicate! and ye who waste
With pale and bloated sloth the tedious day!
Avoid the stubborn aliment, avoid
The full repast; and let sagacious age
Grow wiser, lesson'd by the dropping teeth.
