Jennifer Ackerman wrote Sex Sleep Eat Drink Dream: A Day in the Life of Your Body. It’s about what happens to you and your body during a day. What’s the effect of cafeine on a body? Why do you sleep? What’s the best time to exercise and why should you exercise at all? It’s a great book based on an enormous amount of scientific researches. It reads easily and is interesting all the time. I rate it with an 8.
