Numerous case histories and research data exhibit that healthy life style is key to our longevity and enjoying a healthy and happy life. The primary components of "healthy life style" are: (i) keeping our environment healthy, i.e., clean air, water, and soil (ii) eating right diet (in both quality and quantity), (iii) engaging in regular exercise, e. g., walking, yoga and others, (iv) regularly managing our stress, (v) keeping our spirit healthy, and (vi) routinely tracking the "state of our health." These aspects of healthy life style, supported by research data and case histories, are discussed in detail in this book. In addition, this book stresses that, as responsible health consumers, we should keep track of most recent health related research and recommendations. Finally, the book makes a case that to age graciously and to live healthy we not only need to follow "healthy life style" but must also be cheerful with positive state of mind about our lives.
