124: If a Doctor Lived to 103, You Might Want to Know His "Secrets"
Guinness World Records recognized Howard Tucker as the oldest doctor ever. Dr. Tucker was a neurologist for more than 75 years until his hospital closed in 2022.
Dr. Tucker recently wrote an essay for CNBC and died shortly after doing so on December 22, 2025 at the age of 103.
In my opinion anyone who crosses the centenarian line deserves to be heard.
But a medical doctor, in the brain-health field, that certainly gets my attention.
Questions were frequently asked of Dr. Tucker about how he stayed happy and sharp mentally, and fulfilled throughout his 103 years.
He admits, "I don't believe there is one magic answer. Good genes and good luck certainly can give you a head start. But over the years, I've come to believe there are a few principles that matter a great deal."1
Consider what Dr. Tucker considered "non-negotiables for a long and meaningful life"
From mindset to emotional control to moderation, life, according to the good doctor, doesn't have to be complicated.
Keeping Dr. Tucker's core themes in mind here's his take how to live simply.
Activate your mind
Dr. Tucker would tell his patients that "the mind is like any other muscle in the body: If you don't use it, it weakens." 2
I agree.
Start with what you don't understand or are ill-informed about.
Maybe it's wrapping your brain around the ever evolving digital environment we live in such as social media, AI (Artificial Intelligence), or smart devices.
Push back against the intimidation you feel by schooling yourself on these life-changing breakthroughs.
Your education truly never ends, school's always in session.
Dr. Tucker attended law school in his early 60s, doing so at night after working full-time days as a physician. He passed the Ohio Bar Exam at the age of 67.
"I never set out to break a record. I did it because law, like medicine, interests me and I have always believed it is important to keep learning." 3
An active, engaged mind doesn't require a job or career. Volunteer, read, learn a new skill, play an instrument, join a book club but whatever you do, activate your mind.
Control your emotions
Self-control shows up in diet and exercise, no doubt.
But so does keeping your emotions in check.
"I have been around for a long time. Like everyone else, I experience disappointment, loss, and unfairness. But I never think it makes sense to carry the hatred around with me. Anger and resentment take energy. They take a physical toll. In my view, they do more harm to the person carrying them than to anyone else." 4
Dr. Tucker's insight validates the connection your unmanaged emotions can have on your blood pressure, hormonal stress, and your risk of heart disease.
Plus, have you thought about how much mental energy is consumed by holding onto hate or other toxic emotional responses?
Stay in control emotionally.
Redirect your energy to the people, places, and things that add meaning to your life.
Enhance your enjoyment
Self-denial shouldn't be in opposition to pleasure.
Moderation keeps what you enjoy in balance.
Good food, good drink, and a sensible relationship with those two alone give moderation room for enhanced enjoyment.
Dr. Tucker gave props to his wife of 68 years for being "a wonderful cook,"5 admitting that they always ate well.
"To me, moderation is what makes enjoyment possible over the long run. Having a sensible approach to what you eat. The same is true in many parts of life. Too much of anything can wear you down. Too little can do the same."6
Longevity wisdom is prevalent and those like Dr. Howard Tucker are a worthy source
- Activate your mind
- Control your emotions
- Enhance your enjoyment
