Pick up a paper back book. Bend it in half in one hand and use your thumb to flick through the pages. Time how long it took.
Now, using the same book, read the first word on every page. Did it take you longer?
Reading a file and doing nothing with the lines is the metaphorical equivalent of flicking through the pages.
