The Difference Between Living Longer and Living Well
UroLongevity is a book about the difference between living longer and living well, written by a urologist. That pairing surprises people, and the introduction explains it. A urologist sees men at fifty who did not come in at forty: the bladder symptoms they tolerated, the erections that faded and were written off as age, the blood pressure nobody rechecked. By the time they arrive, the easy interventions are behind them. The book is an argument for starting earlier, and a guide to what to measure.
What the book covers
The center of the book is a small panel of measurements that, read together and over time, say more about your trajectory than any single lab result: VO2max, grip strength, ApoB, and body composition by DEXA scan. Each chapter explains what the measurement reflects. VO2max is the capacity of the heart, lungs and muscle working together. Grip strength is a proxy for total muscle and for the nervous system that drives it. ApoB counts the particles that actually deposit in artery walls, which a standard cholesterol panel only approximates. DEXA separates muscle from fat and shows where the fat sits.
The book insists these are inputs to an estimate of life expectancy, not a scorecard. The point is not to chase a number but to see the direction of travel and change it while it can still be changed. It also makes an honest caveat that a lot of longevity writing skips: the markers partly reflect underlying health rather than cause it. A man with a high VO2max is fit partly because he is well. Improving the marker helps, but it is not magic, and the book says so.
From there it applies the estimate. Screening decisions, prostate cancer screening above all, are keyed to remaining life expectancy rather than to age. A man expected to live another fifteen years should know about a slow-growing cancer; a man expected to live five probably should not be biopsied for one. The same logic runs through colon, heart and other screening.
A full section is given to nocturia and sleep, which the author treats as a longevity issue and not a nuisance. Getting up at night fragments sleep, and fragmented sleep worsens blood pressure, glucose control, mood and daytime function. Nocturia is also often a sign of something else: fluid shifting out of the legs when you lie down, sleep apnea, the heart, the kidneys, or evening drinking habits. Fixing it is one of the highest-return interventions a urologist can offer a middle-aged man, and the book shows how the cause is found.
Hormones are handled carefully. The book explains what testosterone does and does not do, why it should be measured properly and more than once before anything is prescribed, and why replacement is a decision with real trade-offs in fertility, blood counts and cardiovascular monitoring rather than a supplement to add. It is as critical of clinics that hand out testosterone without a workup as it is of doctors who refuse to discuss it.
Who it is for
Men in their forties and fifties who feel fine and want to keep it that way. Men who have been given a testosterone prescription without an evaluation and wonder whether it was the right call. Anyone who has been told to get a PSA, or told not to, and wants to understand the reasoning. Partners and adult children who are trying to get someone to the doctor and need a better argument than nagging.
How it connects to care at NYMD Center
The panel in the book is the panel we run in our longevity medicine program, and we read it the way the book describes: together, and against the previous result. Cardiovascular risk, including ApoB and the tests that go with it, is assessed through our heart and stroke risk factor screening in internal medicine and cardiology. Men who are up at night are evaluated in our nocturia and sleep clinic, where the bladder, the heart, the legs and sleep are considered together rather than in separate offices. The program's own site, urolongevity.com, carries more on the approach. The book is the explanation; the visit is where the numbers get measured.
Questions patients ask
Why is a urologist writing about longevity?
Because a urologist sees the consequences of neglect earlier than most specialists. Erections fade before the heart attack, the bladder is damaged before the man mentions his stream, and low testosterone gets treated before anyone asks about sleep or weight. The book is an argument for measuring the right things at forty so that the visit at fifty is a check-in rather than a rescue.
Is the longevity panel a score I should try to maximize?
No, and the book is careful about this. VO2max, grip strength, ApoB and DEXA body composition are read together and against your previous results to estimate a trajectory. The markers partly reflect underlying health rather than causing it, so improving one does not guarantee a longer life. What the panel does is show the direction you are heading while there is still time to change it.
How does the book treat testosterone?
Carefully. It explains what testosterone does, why it must be measured properly and more than once before anything is prescribed, and why replacement is a decision with real trade-offs in fertility, blood counts and cardiovascular monitoring. It also explains that low levels often have a cause, such as sleep apnea or obesity, that can be treated on its own.
Do I need to be a patient to benefit from the book?
No. The book stands on its own as an explanation of how to think about the second half of life. If you want the measurements it describes, our longevity medicine program runs the same panel and reads it the same way, and new patients are welcome.
