After quitting her job with an awkward text to her boss, Lucie Frost planned to live out her early retirement fantasy. Except she was lost, an empty nester with no job, no structure, no identity, and no clear purpose. Everything changed after she binge-watched the television program 90 Day Fiancé one day, which led to a stream of answers to her question about midlife stagnation: What do we do with our lives when our jobs or children are no longer making those decisions for us? Her trivia-filled memoir, How the Hell Did I Not Know That?, follows the first year of Frost’s postretirement era, a year when curiosity pulled her off the couch and into a world where she discovered how to build a fulfilling life from the smallest of wonders—things like how to unboil an egg with urine (but why, oh why?), where the vice president of the United States lives (something we should know?), and why the sky is blue (wait, didn’t we learn that in third grade?). How the Hell Did I Not Know That? is a witty and honest companion, a girlfriend, if you will, for women in midlife who are struggling to find their place in the world, who are concerned about misogyny, climate change, and the industrial prison complex, just not while watching the latest episode of The Bachelor . Frost shows us that women “of a certain age” need to take themselves seriously while remembering to laugh at inappropriate things and that they can find meaning in life by relying on the power of curiosity.
