Please note: This is a companion version & not the original book. Book Preview: #1 Health is not a fixed entity, but rather something that varies from person to person. It is the ability to adapt to one's environment. Health is not synonymous with a high metabolic rate, but rather a warm body, good digestion, and daily bowel movements. #2 The thyroid is the butterfly-shaped gland located at the front of your neck. The thyroid synthesizes four thyroid hormones: T1, T2, T3, and T4. Each thyroid hormone is made up of the protein tyrosine and iodine. #3 If you have many of the above symptoms, you may be suffering from a depressed metabolic state. Ask yourself: What is your body temperature. How often do you urinate per day. How is your sleep. Your skin, hair, and nails. Your energy. Your mood. #4 Your lifestyle, stress, toxic load, and diet are affecting your health far more than just your years on this planet. In the upcoming chapters, I'll teach you how to improve your health, metabolism, and longevity with some out-of-the-box nutritional and lifestyle changes.
