I remember a colleague mentioning that I would define my 40s as a time when I awakened with pain that had no reason for being.
No overuse in the gym.
No trauma.
Just age.
As I transition into my 60s, I occasionally notice small unpleasant elements.
You may relate: It seems that injuries happen more frequently.
I do not have my historical muscle strength.
A new study provides some insights, revealing what may be behind my physical decline.
In my mid-40s, I noticed aging signs.
It wasn’t gradual; I suddenly realized I was in my 40s.
It seemed that I had rapidly aged.
As I transition into my 60s, I am noticing the same phenomenon.
Or was it just my imagination?
Stanford researchers recently provided some answers.
Was I wrong in my perception that I had experienced a moment of rapid aging?
A new Stanford University (USA) study tracked thousands of molecule types in adults aged 25 to 75.
The researchers analyzed blood (and other biological samples) from 108 subjects.
Here is the main takeaway message:
People tend to have two dramatic aging leaps — the first at around 44 and the second at approximately 60.
Aging appears to happen in bursts.
These changes appeared no matter what type of molecules the researchers analyzed.

Well, I am about to chase a squirrel.
What comes to mind is punctuated equilibrium.
This evolutionary biology theory describes evolution as a series of short, rapid times of change interrupted by prolonged periods of stability.
My Harvard professor, the late Stephen Jay Gould, joined Niles Eldridge to develop this theory of how new species emerge and diversify.
They based their view on fossil record patterns developed by paleontologists.
For those in their 40s, the Stanford researchers discovered significant changes in molecules related to:
Can’t resist sharing this:
“Aging is an extraordinary process whereby you become the person you always should have been.” — David Bowie.
My first thought?
The mid-40s aging acceleration among women might be secondary to perimenopausal (the transitional period before menopause) changes.
The researchers thought menopause might be playing a role until the scientists realized that men in their 40s had similar molecular alterations.
For individuals in their 60s, molecular alterations appeared related to:
The scientists wonder if lifestyle influences the alterations in the 40s and 60s.
For example, folks might consume more alcohol in their 40s, a time of higher stress for many.
Anecdotally, I don’t find alcohol consumption to be higher among my patients in the 40 to 50 age group.
In conclusion, the rapid changes in our bodies during our 40s and 60s are associated with molecular alterations, affecting various aspects of our health and well-being.
Understanding these changes may help you focus on optimizing your lifestyle, including factors like sleep, diet, physical activity, and relationships.
The bursts of aging in the 40s and 60s remind this 61-year-old to stay focused on optimizing lifestyle.
I pay attention to:
My perception of a sudden onset of age-related disorders (including more muscle achiness after working out) seems grounded in reality: We may experience a sudden onset of age-related changes in our bodies.
We don’t understand the full consequences of these molecular changes, but I now better understand my challenges in gaining lots of muscle.
Could it be that the origin of many diseases — that emerge later in life — is related to molecular changes in our 40s?
