In spite of the hearty imperatives of the title, and the hortatory injunctions (""You can"". . . ""You are that person"") of the style, most of this general book about staying healthily ""middle-aged for life"" is full of stern strictures you should not ignore. . . no crash diets, no pills whether vitamins or pep or sleeping, no cigarettes, etc., etc. All of this is eminently sensible advice on eating well but not too much, drinking likewise, reducing tension, exercise, and lessening the threats of the two great killers, heart and cancer, as well as the likelihood of the common cold. Appendix with a very complete nutrient-calorie chart. Nothing faddy, nothing new really, but sound.
