How do people read writing that goes right to left?

When you open a book in English, your eyes travel left across the page, then snap back to start the next line. Left to right, left to right, like a typewriter. But open a book in Arabic or Hebrew, and something feels backwards — the sentences flow the other way. Right to left, right to left. How does your brain even do that?
Here's the secret: reading ANY direction is learned, not hardwired. Your brain isn't born knowing which way to scan a page. When you were small, you trained your eye muscles and attention system to follow English's left-to-right pattern, over and over, until it felt automatic. A child learning Arabic trains the same muscles and attention — just in the opposite direction.
