Your Body: The Missing Manual

Book Description

What, exactly, do you know about your body? Do you know how yourimmune system works? Or what your pancreas does? Or the myriad --and often simple -- ways you can improve the way your bodyfunctions?

This full-color, visually rich guide answers these questions andmore. Matthew MacDonald, noted author of Your Brain: TheMissing Manual, takes you on a fascinating tour of your bodyfrom the outside in, beginning with your skin and progressing toyour vital organs. You'll look at the quirks, curiosities, andshortcomings we've all learned to live with, and pick up justenough biology to understand how your body works. You'll learn:

  • That you shed skin more frequently than snakes do

  • Why the number of fat cells you have rarely changes, no matterhow much you diet or exercise -- they simply get bigger orsmaller

  • How you can measure and control fat

  • That your hair is made from the same stuff as horses'hooves

  • That you use only a small amount of the oxygen you inhale

  • Why blood pressure is a more important health measure thanheart rate -- with four ways to lower dangerously high bloodpressure

  • Why our bodies crave foods that make us fat

  • How to use heart rate to shape an optimal workout session --one that's neither too easy nor too strenuous

  • Why a tongue with just half a dozen taste buds can identifythousands of flavors

  • Why bacteria in your gut outnumbers cells in your body -- andwhat function they serve

  • Why we age, and why we can't turn back the clock

  • What happens to your body in the minutes after you die

  • Rather than dumbed-down self-help or dense medical text,Your Body: The Missing Manual is entertaining and packedwith information you can use. It's a book that may well change yourlife.

The bookcovers pretty much anything you may want to know about your brain,from what makes it up, through how it develops to how to mitigatethe affects of aging. The book is easy reading, fact packed andhighlighted notes and practical applications. So if you want tolearn more about your brain, how it works, how to get the best outof it or just want to stave off the ravages of Alzheimers (seechapter ten for details of how learning helps maintain your brain)then I can't recommend this book highly enough." -- Neil Davis,Amazon.co.uk

And even though the book covers a broad scopeof topics, MacDonald keeps it well organized and easy to follow.The book captures your attention with fun facts and interestingstudies that any person could apply to their own understanding ofhuman ability. It has great descriptions of the brain and itsinterconnected parts, as well as providing full color pictures anddiagrams to offer a better explanation of what the author istalking about." -- Janica Unruh, Blogcritics Magazine
