Ever since it premiered back in July 2016, we’ve all been obsessed with Stranger Things. In case you forgot, the Netflix series stars Millie Bobby Brown, Finn Wolfhard, Caleb McLaughlin, Gaten Matarazzo, Noah Schnapp, Sadie Sink, Natalia Dyer, Charlie Heaton, Joe Keery, Dacre Montgomery and more! It’s a science fiction show about a group of kids who discover supernatural forces and a portal into an alternate universe. And with a plot and a cast that epic, it’s seriously become one of our all-time favorite shows. It’s currently on its third season, and we cannot stop watching.

But we have a pretty important question about the series. And that is — how old are the characters IRL? We went ahead and did some investigating, and the results might surprise you. We mean, it’s no secret that often times in TV shows and movies, the actors are a lot older than their characters, and the same goes for some of the Stranger Things cast.

Scroll through our gallery to uncover the kids from Stranger Things‘ ages in real life, and prepare to be shook.
