For centuries, people have dreamed of longer, healthier lives. Yet modern society still struggles to close the gap between how long we live and how well we live. Many individuals reach their 80s but start experiencing declining mobility and independence decades earlier.
According to Dr. Jin-Xiong She, “The only way to extend the healthspan is through the prevention of health conditions or diseases, and injuries.” His solution is a practical system based on science, rooted in experience, and centered on action.
Closing the 20-Year Gap
Dr. She, founder of Jinfiniti Precision Medicine, has spent his career researching the causes of chronic illness and aging at the cellular level. “In industrialized countries, the average life expectancy is around 80 years, while the average healthspan lags at just 60 years,” he explains. “This 20-year gap is primarily caused by major age-related diseases such as diabetes, kidney disease, cardiovascular disease, and cancer.”
Through Jinfiniti's forward-looking approach, that gap doesn't have to be permanent. “You have to be proactive and take action as early as possible before injuries and disease occur,” says Dr. She. He believes healthspan—how long a person stays healthy and functional—can be extended by 20 or even 30 years.
The TAO of Personalized Longevity
Dr. She’s approach is built around the TAO Principle: Test, Act, Optimize. “TEST—Before you can go anywhere, you have to know where you are,” he says. “Precision testing of biomarkers is vitally important for understanding what you need to do to improve your health.”
Once you've tested, the next step is action. “ACT—You must take charge of your healthspan by making the appropriate lifestyle choices. You must develop a plan and implement it.”
And then comes refinement. “OPTIMIZE—We always want to live in that ‘sweet spot’ where our NAD levels remain in the optimum range. But we also want other aspects of our life to be optimized.”
This isn't a theory. Dr. She, who is 63, applies his principles in his own life. He says, “I'm 63 years old now, and my tennis game is better than it was in my mid-thirties. I used to have to warm up for an hour so I wouldn’t get hurt. And it would take me a week to recover. Now at 63, I can play for 3-4 hours nonstop. I play twice a week.”
Dr. She also lays out this framework in his new book, The TAO of NAD, which blends ancient Eastern philosophy with modern science to help readers create their personalized path to a longer, healthier life. Endorsed by leading doctors and researchers in anti-aging medicine, the book presents data-driven strategies to manage age-related decline and improve resilience.
Rather than offering a one-size-fits-all solution, The TAO of NAD teaches people how to become informed influencers of their own biology by constantly measuring, adjusting, and optimizing with intention.
NAD and the Science of Staying Younger
One core part of Dr. She’s system is NAD optimization, a natural molecule in our cells that declines with age. Short for nicotinamide adenine dinucleotide, NAD is a coenzyme found in every cell of the body, where it has a significant role in energy production, DNA repair, and cellular resistance. NAD essentially helps to power metabolism and supports the body’s ability to stay healthy at the cellular level.
“NAD levels decline during aging, and the only way to know if or how it can be reversed is through regular NAD quantification,” he explains. Jinfiniti was the first company to offer a commercial NAD+ test, allowing patients and doctors to measure and manage levels more precisely.
“We analyze biomarkers, cross-referencing every possible combination to understand how they work individually and in tandem,” explains Dr. She. “Taken together, your biomarkers predict whether you will develop age-related illnesses.”
Your Health, Your Responsibility
Dr. She strongly believes that no one should wait for a diagnosis to take control of their future. “It’s your healthspan, so you must take control. Educate yourself about NAD. Don’t just take my word for it, but look at other reputable studies.”
He encourages readers to stop guessing, start testing, and make health a lifelong project. “Optimization is not a one-shot deal; it's a lifestyle,” he states. “When we slip or trip, we must pick ourselves back up again and recommit to a personalized program of holistic health.”
It’s a mindset shift that redefines what longevity means: not just more years but better ones.
