Of all the things you'd imagine women might have in common, a mid-wrist freckle is surely among the most unlikely.
But empirical evidence is a persuasive tool - if not necessarily a definitive one - and apparently lots of us have a little freckle in the exact same place.
Sounds unlikely? OK, let's explain. Many women responded to a post on Twitter which was shared back in 2019, asking whether the mid-wrist freckle was a myth.
And the pictorial evidence speaks for itself, even if it does seem like it may be coincidental rather than conclusive.
The tweet was posted by Aaryn Whitley, who asked: "Ladies... you got a freckle on the middle of your wrist or is this a myth?"
Her post quickly went viral and racked up almost 30,000 comments - many from women sharing their own freckle photos and others questioning why they all had them.
They are not genetic per se, but, usually if other members of your family get them, you will, too.
Freckles normally develop in childhood and may disappear as you get older or they might stick around and make an interesting Twitter moment in the future.
Why so many women seem to have them in the same spot is anyone's guess.
Maybe it's due to the fact wrists would often on display in the sunshine and would naturally become freckled? Or perhaps it's a mark of an alien sub-species poised to take over the world any day now?
It just has to be the latter, imho.
