There is no definite answer to the question of how many books a person can read in a lifetime because everyone's reading speed and reading preferences are different, and the number of books they read depends on their education, career, and personal interests. Some studies show that the average person reads about 20 to 30 books a year. This number may vary from person to person because some people may be better at reading long books while others prefer short stories and novels. In addition, reading also depends on the purpose of reading, such as to obtain knowledge, entertainment, or enhance skills. Some people can read a lot of books at a time while others can only read a few books. Generally speaking, reading is a beneficial activity that can help us expand our knowledge, improve our language ability and train our thinking ability.
