If you have made a new year’s resolution to get healthier, you’ll find a buddy in David B. Agus’s new book, “The Lucky Years: How to Thrive in the Brave New World of Health’’ (Simon & Schuster). He discusses advances in personalized medicine but he also is a big believer in the value of paying attention to our bodies. He suggests gathering data on your health for two weeks — taking your blood pressure, keeping track of eating and sleeping habits, and noting how you feel every day. After analyzing your findings, you can then focus on the habits that will bring you the most health benefits.
