The Age of Scientific Wellness
Why the Future of Medicine Is Personalized, Predictive, Data-Rich, and in Your Hands, written by Leroy Hood and Nathan Price
Taking us to the cutting edge of the new frontier of medicine, a visionary biotechnologist and a pathbreaking researcher show how we can optimize our health in ways that were previously unimaginable.
We are on the cusp of a major transformation in healthcare―yet few people know it. At top hospitals and a few innovative health-tech startups, scientists are working closely with patients to dramatically extend their “healthspan”―the number of healthy years before disease sets in. In The Age of Scientific Wellness, two visionary leaders of this revolution in health take us on a thrilling journey to this new frontier of medicine.
Today, most doctors wait for clinical symptoms to appear before they act, and the ten most commonly prescribed medications confer little or no benefit to most people taking them. Leroy Hood and Nathan Price argue that we must move beyond this reactive, hit-or-miss approach to usher in real precision health―a form of highly personalized care they call “scientific wellness.” Using information gleaned from our blood and genes and tapping into the data revolution made possible by AI, doctors can catch the onset of disease years before symptoms arise, revolutionizing prevention. Current applications have shown startling diabetes reversed, cancers eliminated, Alzheimer’s avoided, autoimmune conditions kept at bay.
This well researched book is written by people with significant hands-on experience of applying big data to the healthcare industry, so provides plenty of real-world examples of what does, and doesn't, work. The authors believe that we are at the dawn of a healthcare revolution that will shake-up today's healthcare system which is reactive, treating diseases long after they've taken root.
Hood and Price see a future, not too far away, where we can predict and prevent most chronic diseases, shifting the focus from illness to wellness. It's a future where our healthcare is informed by our genome, lifestyle choices, and life history, and where data-rich, AI-powered systems drive diagnoses and treatments. However, this revolution won't be possible without a shift in our understanding of disease and wellness, and a commitment to making healthcare more transparent and accessible.
It reminded me of what an early stage we are in preventative medicine - the average "full" blood panel test today is nothing compared to the thousands to molecules and proteins that we might test for in future to give early warning of disease. Although they don't believe humans will eventually live forever, they are expecting an extra 10-20 years of healthspan and lifespan, and this could bring longevity escape velocity within grasp of millions more people.
Here are 100 key points from The Age of Scientific Wellness.
- We are in the first stage of the largest paradigm shift in healthcare since the beginning of modern medicine.
- In today’s world, medical interventions happen long after a disease has taken hold.
- People who contract one disease are more likely to become sick with another.

- But we do not foresee a future in which we beat back all diseases, altogether and forever.
- The ten most popular drugs in the United States today work, collectively, for only about 10 percent of treated patients.
- Ultimately, a life span and a health span should be virtually the same.
- Human Genome Project saw similar objections to ageing research, including worrying that this enormous project would take resources away from smaller research efforts.
- There are very few processes in our bodies in which A causes B, and B causes C, and so on in a simple, linear manner.
