“Normal Aging Is Optional.” At 73, a Physician Proves It — and Hands High Performers the Playbook in ALIVE AF

Mark Rosenbloom, MD, MBA, trains six days a week, races Spartans, and tests like a man decades younger. His new book argues the decline you call “aging” is mostly drift — and that it is reversible on purpose.

NORTHFIELD, Ill. — September 13, 2026 — Most books about aging promise you a few more years. ALIVE AF: Outperform. Outlive. Refuse Average. makes a bolder, more unsettling claim: the slow fade you have been calling “getting older” was largely optional all along — and it can be reversed deliberately, with the right measurements, in the right order, under the right physician.

The author is his own longest-running case study. At seventy-three, Mark Rosenbloom, MD, MBA, trains six days a week, competes in Spartan races, and carries metabolic markers that outperform men decades younger. He is not a biohacker or a wellness influencer — he is a Northwestern-trained physician and Stanford MBA. After two decades in emergency medicine, treating what happens after health fails, Rosenbloom built the next chapter of his career around identifying and addressing the changes that happen long before that failure. Now he has put the entire system into a book.

“You are not declining. You are drifting — and drift is reversible,” Rosenbloom says. “Almost everything we file under normal aging is the accumulated interest on small failures nobody bothered to measure. I refuse to accept that — for my patients, or for myself.”

Why ALIVE AF Is Unlike Anything on the Shelf

It is written by a practitioner, not a pundit. The author is documenting his own biology at seventy-three, and the results are on the page.

This is not longevity theory from the sidelines. Rosenbloom draws on the protocols, measurements, and interventions he uses in his clinical practice and his own longevity regimen.

It is precision medicine, not wellness. No supplements-and-good-vibes: measurement, sequencing, and physician oversight — an operating system, not a list of tips.

It goes where most authors will not. Rapamycin. Peptides. NAD+. Senolytics. Hormonal architecture. Explained plainly, with candor about evidence and risk.

It is built for people who have run out of average advice — the high performers for whom “eat well and exercise” stopped being useful a long time ago.

Organized into four escalating parts — how strong people quietly fall apart, building the biological base, the advanced protocols that create an edge, and playing for decades — the book moves from inflammation, muscle, and metabolic stability to hormones, cognitive longevity, and the frontier of longevity pharmacology.

“Refuse average” is not a slogan for Rosenbloom; it is a clinical position. “The people I treat did not get where they are by accepting the default settings,” he says. “Their biology should not be the exception.”
