Who invented beds? When did we start cleaning our teeth? How old are wine and beer? Which came first: the toilet seat or toilet paper? What was the first clock? Every day, from the moment our alarm clock wakes us in the morning until our head hits our pillow at night, we all take part in rituals that are millennia old. Structured around one ordinary day, A MILLION YEARS IN A DAY reveals the astonishing origins and development of the daily practices we take for granted. In this entertaining romp through human history, Greg Jenner explores the gradual --- and often unexpected --- evolution of our daily routines.
