It covers the biology of memory, the limbic system, smell-driven recall, and why people remember and forget differently, including childhood forgetting, amnesia, aging myths, and active forgetfulness. It also examines the digital-era brain, the role of sleep, and practical ways to train memory through experiments and fun exercises.
