Walk into any office in the world—tech startup, bank, law firm, doesn't matter. Find someone at their desk, shoulders curled forward like a question mark, eyeballs deep in emails or Jira tickets. Now, put your thumb right between their shoulder blade and spine, just a little up and in. What happens? They drop their shoulder. They let out an involuntary “ooohhh.”  Then—without fail—they turn to you and say: “Do it again.” That, my friend, is the spot . You know it. I know it.
