If you’ve even watched a few episodes of the HBO series Game of Thrones, you know it is an abusive, heart-hardening show. As soon as you get attached, whoops, your favorite character is dead, and you promise yourself you’ll never love again–it’ll only lead to more heartache, after all. But then, you slowly come to realize, maybe this other character will give you new hope–but, nope, wait, they’re also dead. Or are they??? No. They are dead.
Anyway, someone did some science on this, hooking himself up to an Arduino and PulseSensor, then monitoring his heart rate through the recent episode “Rains Of Castamere” and overlapping it with still images. Now I will spoil the episode, so please avert your gaze if you haven’t seen it.
Two of the main characters are killed off at a wedding (called the “red wedding”) toward the end of the episode. And look at that spike! We can only infer the accompanying tears from the graph here.
