When to sleep, eat, work, exercise, have sex, etc.

According to Dr. Michael Breus, everyone is genetically predisposed to follow a certain sleep pattern. Whether you are an early riser or nocturnal, normal or an insomniac, Dr. Breus can show you your healthiest and most productive schedule in his book The Power of When.I took his quiz here, learned my chronotype, then read the book. It was a really quick read because three-fourths of the information is irrelevant when you know your chronotype. However, I found this book valuable because Dr. Breus showed me how to align my routine with my biological clock and energy fluctuations throughout the day.
