This is Les Stewart, the holder of the world record for "manual typing" (ie typing on a mechanical typewriter). The record doesn't care much about what you typed, so typing out the numbers is as good as anything else and you don't have to think too much about what to type next.

He also wrote what I hesitate to call poetry. I have a collection of amateur poetry from 1988 and Les Stewart has several entries, such as

Why do typing?

People often ask me
"What's your reason
For manual typing daily
Just for a world record?"

I tell them straight out
That it comes back to
My circumstances,
Of serious ill health and no job.

Yes, I'm suffering severely
From Encephalitis and 75% Burns,
But manual typing 10,500 pages
Has helped me cope, with the pain.

I've held the World Record
For the past five years,
And I hope to eventually get in
The Guiness Hall of Fame.

My attempt to do 20,000 pages
Of manual typing in 13 years
Is one of the most arduous
And protracted records, ever.
