Reading books is a good alternative to reading online or using devices since it does not require looking at a screen. Also, books take a long time to read which requires patience and the ability to pay attention to detail and think deeply. As result, books can help us become better thinkers.
Books, especially fiction books, can help exercise the imagination and can also be used to teach lessons about life. Research has also shown that reading physical books is better for comprehension. As result books are a good way to absorb important information that you may be learning in an educational context.
Reading can also improve vocabulary since, as you read, you come across new words that you may have not previously heard especially if you read older books. Reading can also improve writing skills. Many writers learned by reading the works of other writers, so being a good reader is integral to being a good writer.
