Every family has "chemistry" the intriguing and sometimes troublesome blending of emotional and genetic predispositions that shapes each member and the family as a whole. Why do some families suffer from cancer, depression, or chemical imbalances while others do not? Do genetic factors predispose one person to alcoholism while another escapes? Could part of the answer involve a biological mystery that science is just beginning to unravel?

Drs. David and Sharon Sneed present fascinating new research on the power of "family ties." They offer insights to help you understand why you are the way you are. Here you will learn how to construct a family tree that will unlock the secrets of your family chemistry: the temperaments, strengths, weaknesses, and predispositions that, together, make up who you are. Armed with these insights, you will be able to identify those inherited traits and qualities that you value and those you may wish to change.

This provocative and ground-breaking book is not about your unchangeable "destiny," rather it is a resource full of advice and tools to assist you in self- understanding and to help you make healthy choices for your future.
