The Other Side of Peak

When bread goes stale and soda flat
And milk begins congealing
Or mold appears on hunks of cheese,
It’s really not appealing.

We know that chirping smoke detectors’
Batteries have died
And lightbulbs’ lives are over
When a rattle’s heard inside.

It’s obvious when objects
Are no longer at their best.
A glance, a sniff, a noise or lack
Confirms what we have guessed.

But how to tell when humans
Reach the other side of peak?
They’ve bypassed retro and can now
Be classified antique!
