Fat, Fit, and (Almost) Fifty is the second in a collection of books focusing on the seven deadly sins. In this book, the sin of anger is almost enjoyed by Irish-American Catholic lawyer Rosemary McFadden. Rosemary is furious at the entire legal profession, aging, weight gain, poor fashion sense, petty adults, and boredom in suburban Philadelphia. To forget her anger, boredom, and imminent fiftieth birthday, Rosemary dares herself to go way out of her comfort level of daily cocktail hours to martial arts, triathlons, and extreme exercise. The new adventures make Rosemary temporarily forget about growing old, but every muscle in her body hurts.
