I don't have any scientific backing for this, and I'm just totally musing here, but I really feel like there are people who are addicted to cortisol and high blood pressure.

They stay abreast of the 24-hour news cycle and farm outrage from millionaire media personalities from the moment they wake up until the moment they go to sleep. If things are too calm, they start heated discussions and arguments until they've had their fill, exhausting everyone around them with their constant grousing and grumbling.

Not all stress is bad, but I think the kind of stress where you're constantly seething at the state of the world around you is simply a waste of time unless it's your business to know. Especially in American politics where so many stories are really reporting on attention-seeking trolls. Don't give them what they want. Stay awake, stay informed, but don't submerge yourself in it until it becomes your whole personality.
