Remember when your English teacher dropped the bombshell that Romeo and Juliet were technically children, with Juliet estimated to be around 13, while Romeo was pushing on 16, and it freaked you out a bit?
The kids fell in love, got married, then killed themselves around about the same age we were cracking open our first bottle of Barcardi Breezer.
Anyway, prepare to feel that shock all over again because we've just learned how young Game of Thrones' Jon Snow And Daenerys Targaryen are meant to be.
*Spoiler alert*
As we now all know, Daenerys is Jon Snow's aunt (Ned Stark's sister, ran away with Rhaegar Targaryen, Dany's much older brother and, to cut a long story short, Jon was born) so we kind of suspected the Dragon Queen and her nephew might be around the same age.
But we thought, given their travails and presumably years of trudging around that have passed so far, they'd be early 30s by now – maybe even a tad older.
Yet according to Game of Thrones Wiki fan page, Jon was born in 281 AL (AL = Aegon's Landing) and Dany was born in 282 AL, so there's actually just one year in age between the pair.
Season 7 of the hit show is currently set in the year 304 AL, which makes Snow approximately 23 years old and Dany aged 22, give or take a few months.
What now?
