Sport Science S02E11: World’s Toughest Woman (June/21/2009)
"Gina can land all 8 blows in a blistering 3 seconds. And how much does this maelstrom combine to generate? An amazing 4,800 pounds of force. That’s like a North Pacific giant octopus pounding you with all 8 of it’s arms. Translation: In 3 seconds, Gina could brake your ribs, give you a concussion, shatter your nose, rupture your spleen, cause internal bleeding, and put you down for the count."
There’s actually a whole point about this in these Harry Potter analysis books I used to read obsessively. Two of their cardinal rules of HP foreshadowing are “Hermione is always right, except when she’s emotional” and “Ron is always wrong, except when he’s joking”. This actually plays out pretty frequently in the series if you look for it!
