Im no physician, I dont know.
My chiropractor made a small suggestion that a walk in the forest could help, and I discarded it because I was already “walking in the forest” a lot. Except I kept to the well-trodden paths. And I walked on asphalt to get to the forest. And it didnt really help. And the exercises he told me to do at home didnt really do much.
It isnt just how Markdown works either, its how HTML works too: Text is grouped in paragraphs there too, not in lines or statements. Of course there is options to force a line break for when its necessary. But most text reads better as paragraphs. And most people overuse manual line breaks.
