Mental Efficiency and Other Hints to Men and Women by Arnold Bennett, a British novelist, is an amusing book of instructions for the readers of all generations and times. Bennett argues that we focus on keeping ourselves physically healthy and we spend a lot of time, effort and thought into keeping the body in fine trim. However, in the race to become more muscular, youthful and bright-eyed, we often neglect our mental health. Concentrating on one part of ourselves and ignoring another can have disastrous effects. Therefore, we brought here a book by Arnold Bennett, one of the most acclaimed authors of his time, which would guide the readers in a direction to improve and maintain their and their loved ones’ mental health.
