Book excerpt: Use this Family Medical History journal to compile information about your grandparents, parents, uncles, aunts, siblings, cousins, children, nieces, nephews and grandchildren. Lots of unanswered questions? Take this journal to Thanksgiving, Christmas and other holiday get-togethers. Your doctor might use your family medical history to assess your risk of certain diseases. Go to your doctor appointments with information on hand, and look ahead to the future, when you may not be around to share this information with your own children or relatives.
