After Shakespeare

“Brain has five ‘eras’, scientists say—with adult mode not starting until early 30s:
Study suggests human brain development has four pivotal ‘turning points’ at around the ages of nine, 32, 66 and 83″
—The Guardian

Update: the world—in other words, the brain—
Has stages, yes, but scientists explain
That those old seven are in fact chimeras:
Five’s the true number of our mental eras.
First you’re an infant, puking still and mewling.
Then you turn nine and gripe about your schooling.
At thirty-two, you’re all grown up, so show it
By acting like a soldier, or a poet.
At sixty-six, it’s time for eating chicken
And learning law. If still alive and kickin’
When eighty-three comes round, your life’s adventures
Will shrink to hunting slippers, specs, and dentures.
So that’s the scoop. Of course you’re free to spike it;
We know truth isn’t always as you like it.
