> You don't have to be taught to breathe.

That’s where I would disagree. Sure there’s a baseline of breathing that everyone does otherwise they’d be dead, but I think the ceiling towards skillful breathing is very high. The difference is more obvious under athletic conditions like if you’re running or biking, just improving your breathing rhythm can improve your performance. There’s even a proper way to breathe if you’re weightlifting, some people might pick it up naturally but I know it’s also commonly taught.

In psychology I’m pretty sure it’s well established and not pseudo science that certain breathing rhythms can increase your energy or decrease your anxiety, I think I read that they teach box breathing to some parts of the military to help keep them calm during missions.

So there’s definitely a range of breathing ability for specific tasks.
