Medicine with a Ring

In Patriot Games, Admiral Greer, played by James Earl Jones, corners Jack Ryan with an ancient question: “What in life can you be sure of?”

Ryan doesn’t cite career, country, or gold. He answers without hesitation: “The love of my daughter.”

In a world governed by impermanence and calculated risk, Ryan named the one currency that isn’t transactional: unconditional devotion. Greer was probing character, but modern epidemiology suggests the admiral was probing human survival.

We spend fortunes on statins, gym memberships, and organic produce, chasing biological certainty. Yet decades of clinical data reveal that one of the most potent life-extending therapies in existence slips quietly onto the left ring finger.

The survival numbers are staggering. A massive meta-analysis of over one million patients published in the British medical journal Heart revealed that unmarried adults face a 42 percent higher risk of cardiovascular disease. Following an acute heart attack, married individuals are 14 percent less likely to die in the hospital and are discharged days earlier.

The American Stroke Association reported that chronically single or divorced adults carry an almost 70 percent higher risk of fatal stroke. In oncology, a Harvard study of 735,000 patients in the Journal of Clinical Oncology found that for several major solid tumors, the survival advantage of marriage exceeded the published benefits of chemotherapy.

Does casually living together deliver the same protection? Statistically and biologically, no. Cohabitation studies consistently reveal higher baseline stress hormones, poorer preventative follow-up, and mortality rates that look closer to chronically single adults than married spouses. Sociologists call it “sliding versus deciding”—sliding into convenience rather than deciding on permanent devotion. Those informal arrangements historically face a 33 to 48 percent higher breakup rate.

Did you hear that, ladies? And gentlemen, take note: that gold band isn’t just sentimental jewelry; it’s an evidence-based medical device.

The body knows the difference between convenience and a vow. Unconditional commitment delivers deep vagal tone, flooding the nervous system with parasympathetic signals that lower arterial inflammation and slash cognitive decline risk by over 40 percent.

Living in a building with a historic ballroom, I watch couples tie the knot three or four times a week. There is something timeless about making it official before the community—a public declaration that says, “we belong together now, through thick and thin.”

Part of it is what clinicians call loving surveillance: the spouse who spots an irregular mole on your back, ensures the blood pressure pills are taken, and marches you into my exam room. But deeper still is the autonomic tranquility that comes from knowing you are not navigating mortality alone.

In the movie A Bronx Tale, the neighborhood boss pulls a young man aside to dispense some hard-hitting street philosophy: a man only gets three great loves in a lifetime, and the goal is to make sure the third one is the keeper. Sonny was talking romance, but modern epidemiology suggests he was handing out preventive medicine.

Stanford University’s How Couples Meet study shows modern romance has largely moved to impersonal digital screens. Yet lasting devotion often blooms where pretense has already fallen away—like a milestone high school reunion, where reconnecting mid-life classmates boast a 70 to 75 percent relationship staying power.

What can you be sure of in this life? Biology offers few guarantees. But if you have someone waiting on the other side of the door who shares your vows, thank them tonight for keeping your arteries clear. That gold band is more than sentimental jewelry; it is medicine for the heart.

Is it any wonder though that God’s plan for us to marry, form life commitments with a family and raise children will indeed strengthen even our health.

Well, we know that marriage is work but it can also be said that the meaning of life is work.

Genesis 3 provides the details of how Adam and Eve were kicked out of the Garden of Eden. In it we learn many things including these two basics... Due to their disobedience, they will now eventually face death and the second is that they are now going to have to work.

Genesis 3:23 Therefore the Lord God sent him forth from the garden of Eden, to till the ground from whence he was taken.

Dear Jim,
Thank you for taking the time to write in and share your thoughtful reflection on the column. You raise a legitimate critique, both scientifically and scripturally, and I appreciate the opportunity to clarify where medicine and faith meet on this topic.

From an epidemiological standpoint, you are entirely correct: correlation does not equal causation. In public health research, we call this the “healthy user effect” or reverse causality—individuals who possess the emotional stability, physical vitality, and resources to commit to marriage or care for a dog are often healthier to begin with.

However, preventive medicine does not rely solely on observational surveys. Over the last few decades, neurobiology and cardiovascular medicine have uncovered direct, measurable biological mechanisms behind human connection. Regular, positive companionship stimulates the parasympathetic nervous system, prompts oxytocin release, dampens chronic sympathetic tone, and significantly reduces baseline cortisol and inflammatory markers like C-reactive protein.

Conversely, sustained chronic isolation acts on the body as a continuous physiological threat, accelerating vascular inflammation and endothelial damage. Examining these mechanisms is not a matter of endorsing marriage or pet ownership as magical remedies, but of understanding how our biology reacts to companionship versus isolation.

Scripturally, you cite Matthew 6:27, where Jesus asks which of us, by being anxious, can add a single hour or cubit to our span of life. I could not agree more with your stance on God’s sovereignty over life and death. Our days are in His hands. Yet Christ’s Sermon on the Mount was not a warning against practicing good medicine or wise bodily stewardship; it was an exhortation against the futility of anxiety (merimnaō). Worry cannot add a day to our lives—though unmanaged, chronic distress can certainly exact a heavy physical toll on the body God entrusted to us. Scripture itself frequently connects earthly wisdom, peace of heart, and physical vitality, reminding us that “a joyful heart is good medicine, but a crushed spirit dries up the bones” (Proverbs 17:22).

Advocating for marriage, strong friendships, or adopting a dog is never about circumventing God’s sovereign timeline. Rather, it is an acknowledgment of how the Creator engineered the human nervous system: designed from Genesis for fellowship and community, rather than the destructive wear and tear of isolation.

I am grateful for readers who read carefully, challenge ideas thoughtfully, and take both Scripture and truth seriously.
Warm regards,
Dr. Nick
