Being stressed/angry releases chemicals into our blood and activates the fight o flight response. It increases cuore rate and blood flow, makes us feel like we have to do something. Slamming the door and leaving, shouting, punching someone, o if you're a wimp like me you're not used to expressing that you're angry and break down and cry instead. Being angry clouds judgement and makes it difficult to focus. Thoughts are too hard, let's go with science and a picture of a guy looking like he's shitting himself while squeezing a red ball with a weird face.
If te pay attention and think about politics te will get to know that so many cheaters are there who cheats the system and because of them so many people have to suffer it will of course make te angry!
