5.0

A slew of longevity books hit the markets over the last few years, each with interesting specifics about what can be done to extend the clock on our lives. Attia expands on these earlier writings in two ways. First, he perfectly frames the iterations of our healthcare system - 1.0, 2.0, and now 3.0. Additionally, he looks at numerous specific recommendations (drug trials and human demographics for health conduct) but also takes a long hard look at two behaviors that are the core of best practices for a long, healthy life - diet and exercise.

American healthcare is now in the midst of 2.0, which treats symptoms once they arrive. Sick care extends a sick life, but not by much. Attia knows that early intervention into visible problems much earlier in life leads to less sick care and a longer and extended healthy life healthcare 3.0. The main challenge of 2.0 is that it may extend lives by many years, but those years will still be sick years. Instead, 3.0 extends lives with unhealthy years, focusing early on issues produced by poor health behavior and early recognition of sickness indicators.

The picture drawn of the maturity levels of healthcare may be the most important message to the patient. If your current care is via a 1.0 or 2.0 doctor, and even if you are relatively young, finding a 3.0 doctor could extend the healthy years of your life by a couple of decades. -Tom L.
