Most modern practice involves simply waiting for something to go wrong and then treating only the symptoms of the problem rather than the cause. The Life Extension Revolution goes beyond this mentality and strives to provide a comprehensive look at the aging from process, and things we can do everyday to help halt and even reverse it. With a focus on blood testing, Dr. Miller gives many real case examples of people he's worked with and the regiments used to help them. I found it very detailed without being too scientific - it'd make an excellent read for anyone interested in taking a proactive approach to aging (and his/her doctor as well).
