I have to post this (feel free to fill it up with negs) because I only watched 10 seconds of it rushing around scrolling through it, then closed it, then went in my bed pretending to want to watch an NBA game, then 30 seconds later rolled around in my bed crying like crazy for a long time. One of the most horrible videos I have seen, it absolutely hit me straight into my soul.
Back when I was 17 or so I would "warm up" for 50 minutes. Meaning, the sports teacher would make us do all kinds of drills for 50 minutes and then let us play ball for 2 minutes. And then the hour was over.
And I remember how extraordinarily tired I was after those 50 minutes and yet I could jump like crazy, in a full sprint, because of that warm-up.
