Let’s Talk Bookish: Book Stopping Places

Are you the type of reader able to stop reading just anywhere? In the middle of a sentence? Paragraph? Or do you need to reach the end of a chapter before stopping?

I can pretty much stop anywhere (too tired, don't have enough time or mental power...). If I'm reading physical books, I'll try to finish the page. If I'm reading ebooks, I'll finish the sentence/paragraph. Ebook readers can remember my last reading position, so it's more convenient. However, if I leave it for too long, I mat give it up because I no longer remember what has happened.
