Hi Michael, as you monitor so accurately, could I ask you what in average is the difference between your Phenotypic Age (Levine) and your CA? Over which period of time?

You must have that number, averaging over all years since you report to us. I do not recollect you gave this (apologize if I am overlooking ...).

If you have enough points you might also detect a trend in that differential.

Hi albedo, for the 12 tests prior to the most recent test, 16.0y (n=12). But, last week I had my best results ever (3/4/24 test), 19.5y CA-BA...

Video coming next week!

Thank you for sharing Michael.

For what it matters and be of significance, my data show -13.2 years in average, 2.1 years STD, over 18 years (50-68), n=20, flat (no trend downward or upward)

Feel free to comment!

Thank you Michael. Looking at your data and even considering error bars my bet is you are seeing a real downward effect on your BA using Phenotypic Age. Don't you?

Wishing you all the best can keep your -19.5 years difference!

It would be great if you confirm your downward trend, Michael. As mentioned, I am flat for the the time being but at least not doing worse. Please have the trend in mind in your considerations and the statistics of your data to extract the signal. It would be very interesting and a great topic for a next video.

 

Here is a cohort of people, followed longitudinally, showing different trends using Levine's Phenotypic Age we both use:

Also, while I was familiar with the paper, I hadn't seen this image, thanks for that!

Agree Michael. I attended one a Snyder's presentation and he was kind of presenting that slide as a validation point so maybe it is understandable it often goes overlooked at first sight.

They indeed write:

 

"...Finally, as an independent examination of age, we used the published
phenotypic age formula to assess whether a reported aging
metric changes with time at a personal level27,28. Although overall
phenotypic age increased with age as expected (slope = 1.07), consistent
with the results presented above, the individual phenotypic
age slopes differed among the different participants, with 15 participants
even showing negative values (Fig. 3e). These results using
an independent metric further suggest that individuals are aging
at different rates as well as potentially through different biological
mechanisms.
These results indicate that individuals can have distinct aging patterns,
or ageotypes. To systematically analyze the individual aging
patterns, we further analyzed the 608 molecules that significantly
correlated with age in at least six individuals (see Supplementary..."
