i want to buy this book; so many interesting things that i want to annotate / remember
standout topics:
-evolution of sleep, poses question of why sleep evolved but also why (when considering all the benefits sleep offers) species even wake us at all
-REM sleep has evolved independently multiple times, (like eyes) implying it's importance
-when sleep deprived, species seek nrem first then rem in subsequent days
