An analogy I've heard in the past is that emotions are like a button fixed in a box with a ball in it. When you're younger the box is smaller so the ball hits the buttons more often as there is less free space. As you grow, your box grows too, so your ball has more space in the box and more empty space on the walls for the ball the bounce off of, making the buttons less likely to be pushed.
That analogy seems a bit contrived, but the "button pushing" reminds me of something. At a recent dentist visit the Lidocaine local anaesthetic was accidentally injected into a (small) artery. That's when I discovered that it's a mixture that includes adrenaline, which contracts peripheral blood vessels, preventing it from dispersing too fast. Unless.. it goes directly into an artery, sending it straight into circula…
