Yet most of the artists in all of human goddamn history somehow keep getting this wrong.

We're also not totally sure about those thigh muscles.
In a 2014 study, scientists discovered that, throughout most of human history, the majority of artwork portrays people running or walking by having them extend the arm on the same side as their forward leg. Nobody actually walks this way -- if you try, you'll look like a drunken robot -- and yet it's how artists from every era of history have perceived human movement from ancient Greece, to medieval anatomy expert Peter Paul Rubens, to goddamn Leonardo da Vinci.
Even Mr. Tambourine Man proved fallible.
In fact, it's been noted that cave people had a better grasp on leg position for both humans and animals than we do today. So in terms of understanding biological movement in general, our whole species has been sliding backward since the caveman days. Or maybe it looks more dynamic to depict movement this way and we should quit nitpicking art so much. Your call.

Zoroastrianism used to be one of the biggest religions in the world, but their idea of heaven had a slight twist on it: to get there you'd have to cross a bridge. Sometimes rickety, sometimes wide and sturdy, if you fell off you'd go to the House of Lies for eternity. Fun! Not terrifying at all!
