<p>Ways to place people’s ages:</p>
<p>1.) The person uses a double space after a period (or other terminal punctuation), and occasionally, a lowercase L for the numeral 1.
Explanation: if you learned to type on a fixed-space device – a typewriter – you were taught to use two spaces after a period. One space after a period is the preferred style for proportional-space font, which is what everyone using a computer for word processing has been using for a couple o’ decades, at least. Many typewriters didn’t have a number 1 key; the lowercase L was used for the numeral 1 instead. People under the age of about 50 would be completely puzzled about the use of L for 1. People my age (over 50 by some) might have used an L for a 1 when young, but might still occasionally revert, by some primal muscle memory, to putting two spaces after a period. People who are over 60, and my exH who is 54, may habitually put two spaces after a period; it’s hard to retrain oneself for some tasks!</p>
<p>2.) The person uses either “in like flint” or “in like Flynn.”
Explanation: The “Flynn” in “in like Flynn” (purportedly) refers to Errol Flynn, a movie actor of a bygone era. “In like flint” was a pun on this and refers to a more recent couple of movies. Older people will say (or type) “in like Flynn,” and if they are women, may sigh in memory of the actor; younger people will say (or type) “in like flint.” Sighing is unlikely.</p>
