"I haven't done a book for about 3 or 4 years now"

Gerald Scarfe's quote suggests that he has not composed a book in the past couple of years. This might be due to a range of factors, such as a lack of inspiration, an absence of time, or a lack of motivation. It might likewise be that Scarfe has actually been concentrating on other jobs, such as his art work, and has actually not had the opportunity to compose a book. It might likewise be that Scarfe has actually been taking a break from writing and has been focusing on other elements of his life. Whatever the reason, it is clear that Scarfe has not composed a book in the previous couple of years. This might be a temporary break or a permanent one, but it is clear that Scarfe has actually not been composing books recently.
