The best marker for biological age is…

I have recently been interested in cosmology which led me to seek out some great minds in theoretical physics. I will be posting about them soon.

I noticed a certain reverence for Einstein which is well deserved but Einstein himself made mistakes. We tend to learn from discourse and mistakes, not from isolation as explained in this lecture. Einstein was a ping pong player; Newton was a golfer.

I recently received a personal rebuff in one of my blogs:”Ed Park, I me, mine. Where is the peer review?” I would like to confess that I am not an expert scientific research and only a yeoman blogger and lecturer. To me, peer review is a valuable took but not an accelerant to paradigm shifts because like truly original endeavors, like Ravel’s Bolero, Van Gogh’s painting, or Dylan’s unplugged music, it is often reviled when first introduced.

However, don’t consider the source but rather consider the logic instead. My unusual gift is my freedom to abandon my personal beliefs in search of a more perfect union of ideas.

All this is a preamble to my top ten list of biomarkers of aging:

10. Horvath’s epigenetic clock.

-It measures changes in methylation that correlate with cell lineage age

9. CITM – carotid intimal thickening measurement

-over the course of a lifetime, your carotid arteries tend to thicken (see #5)

8. Vital capacity of the lungs

-you lose lung capacity as you age

7. Flexibility of joints

-you lose joint flexibility as you age. See the restoration of spinal flexibility in this video

6. Cognitive flexibility

your brain becomes less agile. We quantify this with the CNS Vital Signs test

5. Pulse wave analysis of arterial stiffness and cardiac efficiency

-the arteries and therefore the pump that supplies them tend to become less elastic and propulsive

4. Telomere measurement of white blood cells

-caveat: survivor bias of damaged stem cells leads to lengthening and mixed averages

3. Measurement of immune senescence

– depletion of stem cells leads to depletion of the immune reserve

2. Genetic homogeneity and number of bone marrow stem cell

-your genetic savings account becomes depleted and damaged over a lifetime. See this 115yo lady with only two stem cell lies left.

1. and the winner is…Chronological age

-yep, it turns out that even with refurbished parts, mileage matters. Sure, there are notable exceptions like my patient, Doug. I still maintain that the other markers except epigenetics tend to deteriorate because of telomere erosion in stem cells but there is no denial of the predictive value of mileage in all but the progeric kids affected with telomeropathies.


Are you disappointed to learn that I believe the best measurement of biological age is chronological age? You need not feel that way.

The reason a Horvath clock has high correlation with chronological age is because they are measuring the survival of a lineage of cells. Dr. Horvath showed that progeria-affected kids who have undeniable biological aging have young epigenetic and chronological ages. He disregards this finding maintaining causation from correlation. I respectfully disagree. I believe this “glitch” in the data implies that telomerpathies that underlie those conditions are still the most robust explanation for aging globally albeit not a terribly useful predictor of health and longevity as they are currently being used.

In my practice, we can measure all of the ten biomarkers of aging and that was the reason I was contacted by a gentleman in Las Vegas needing them for his GDF11 therapy baseline. That said, I truly believe that rather than treating a biomarker, we should ask ourselves daily- “Am I healthy? Do I have space to create and enjoy? Am I off medications? Am I hopeful?” If the answer is yes, despite any measure of aging, you are still young enough.

If you want to learn why telomeres are still one of the most useful markers of aging in both prematurely and normally aging people, watch this video. I am not saying I was wrong…just that my thinking is always allowed to evolve because I don’t lose gravitas like some august tenured Princeton professor. I’m no Einstein but what I do share with him is my ability to find new discoveries when I realize my models are incomplete.

I graduated from Harvard with honors in Biological Anthropology prior to earning my Medical Degree and Masters in Public Health from Columbia University.

In 2007, I became the nineteenth patient to sign up for the use of a herbally-extracted telomerase activator.

The results were so positive that I founded Recharge Biomedical Clinic in 2008 and have since become the leading medical expert in this exciting new field of regenerative medicine treating over 1,300 patients with this exciting new telomerase activation medicine.

I won two Houston Film Festival Awards for my screenplays about Hypatia of Alexandria and Ed Brown of Kentucky.

In 2010 I wrote and self-published a Sci-Fi Graphic Novel called MAXIMUM LIFESPAN

In 2013, I wrote and published "Telomere Timebombs; Defusing the Terror of Aging"

  1. Maximized tissue cell life to minimize stem(with minimized copy deterioration) cell duplication from all sources(stress, chem, radiation, sub par rest, atomic/molecular(ultimately the “smallest” nuclear structural construct entity configuration per tissue type identity) hyper or hypo inaccuracies-diet consumption, etc. maximizing stem cell telomerase telomere eternal maintenance and minimizing telophase mutational stem cell dysfunction. Seems to cover the gist of it.
