The weight of the book matters. Remember your school childhood and a heavy briefcase full of books. Often these portfolios are worn carelessly on one shoulder, which leads to curvature of the spine and other health problems.Books in electronic form are cheaper.E-books do not harm your health. If you bought a “reader” with a good screen, then your eyes will not get tired, because, as a rule, the font of the text on such a “reader” is very similar to the newspaper.An equally important property of e-books is that they help to preserve nature. Think about how many trees it takes to produce one book with a circulation of 3000 copies? And how many harmful emissions into the atmosphere result from the work of printing houses?Each book you read has the effect of remembering the cover, page texture, font size. All publications are different and unique, and together they create a huge world.Paper versions of the publications evoke positive emotions from the smell of book pages, with incomparable pleasure from acquiring the long-awaited volume in a beautifully illustrated cover, considering bindings on shelves of the home library.
