And the years .. also die

It is written on the front cover of this book that it is an autobiography of the author. Do you see to what extent the phrase applies to what was said by its author? Is it an autobiography, memoirs, or notes written by its author over successive years of his life? He moved from a child to a boy and a young man until he was close to seventy. He did not release his book to the people until he had become more experienced and mature, and he had dozens or even hundreds of secrets that he had hidden from others for years. They were written in different linguistic vocabulary, each of which expresses the year in which each number of pages is written. When he was over sixty, the writer was overcome with courage and took out his book, repeating: Let them say what they want about me. They are doing what they can to me, as I have become almost unfit for human consumption in all its forms.Do you think he was honest in what he wrote, or did he hide a lot of prohibited things that cannot be revealed?
