These sort of articles need a gigantic preface: you’re talking about a minute portion of the population who gives a damn enough about things to legitimately push themselves hard enough to suffer consequences from doing so.

For rest of the population, they aren’t pushing themselves anywhere near close to their limit. They don’t even know where their limits lie.

People can stress and get ulcers from whatever. But to be wired in a way where you are stressed because you’re not at the top of your game and you think you’re losing it, is a certain kind of personality.
