“Clever and entertaining . . . contains everything you’d want to know about the ticking away of seconds, minutes, hours, days, years, decades and centuries.” —Time.com Our relationship to time is complex and paradoxical: Time stands still. Time also flies. Tomorrow is another day. Yet there’s no time like the present. We want to do more in less time, but wish we could slow the clock. And despite all our time-saving devices—smart phones, AI, high-speed trains—Americans feel that they have less leisure time than ever. In an era when our time feels fractured and imperiled, The Book of Times encourages readers to ponder time used and time spent. How long does it take to find a new mate, digest a hamburger, or compose a symphony? How much time do we spend daydreaming, texting, and getting ready for work? The book challenges our beliefs and urges us to consider how, and why, some things get faster, some things slow down, and some things never change (the need for seven to eight hours of sleep). Packed with compelling charts, lists, and quizzes, as well as new and intriguing research, The Book of Times is an addictive, browsable, and provocative look at the idea of time from every direction. “Alderman’s greatest achievement is the continual delivery of quirky knowledge that our collective curiosities crave.” —Forbes “Fascinated by how we spend—and waste—our most precious commodity, journalist Lesley Alderman gathered the sometimes-surprising stats for her debut, The Book of Times.” —People “A fascinating foray into familiar terrain and a revealing look at how we really spend our lives.” —Mental Floss
