I still find people who do this
(slrpnk.net)
At my last job, a bunch of the older folks did not realize they had a "two spaces" habit.
It's a clear tell.
Saw this meme and thought I'd point that out.
Someone born in 1976 is either 48 or 49 right now, which is well inside the "two spaces" era. So you've go a couple more years to clear these folks out before its an "over 50 thing".
