We are not born old. We worked to get there. And it is such a surprise when you realize that your new body has been absorbed by a different one; freckles aren’t where they used to be, and parts that were visible are now obstructed. It’s a jarring moment, full of terror, anger, and wonder. It happens to every single one of us who stays alive long enough. But no one sits down and has the Talk with you about how your body is changing, your hormones are dying like they’re on a muddy battlefield in France in 1917, and you’re about to enter a new phase of your life.
