Is English composition e-book or paper book better?

I like paper books because I like to hold them in my hand. However, e-books may have some negative effects on health.

Just say that e-books may affect health problems. When we read books online, we often get a certain amount of radiation. (actually, there is not much radiation. Generally, large ones are replaced by large ones. Large generally refers to the size of an object. I use a certain amount here, because there is some radiation, but it is not very big. Paper books make me feel familiar (here you can use familiarity to express your intimacy with books, which means familiarity. Or it can be said that paper books make me feel real. I like this sense of belonging when reading paper books. From the collection point of view, e-books are not very valuable compared with paper books. (You can use collection and save to get the collection value. Like saving money or saving lives. A reader who has bought hardcover books once said: Although it is more expensive to buy paper books, you can read them before collecting them, but you can't really collect e-books. From the point of view of sharing, although e-books are quickly shared online, it is not convenient in the sense of borrowing/lending between friends. These are some reasons why I like paper books.
