If you want to know your chronological age, simply count the candles on your next birthday cake. Calculating your biological age, though, is a little more complicated.
Chronological age is the number of years between your birth and now; it's purely time-based. Biological age, on the other hand, describes the progressive breakdown of an individual's physiological and molecular systems over time; it's a measure of how "aged" the body is. The calculation aims to answer the question of how well your systems, organs and cells are working compared to an average, healthy baseline.
"Biological age is notoriously hard to define because it's very much a conceptual notion," said Eric Sun, an assistant professor of biomedical engineering at MIT, where he will launch a new lab starting in 2026. The concept requires you to think less about pure chronology and more about how your body is performing over time, and what your risks and vulnerabilities for various diseases might be in the future, he said.
Scientists have devised a number of "clocks" aimed at determining people's biological ages. Here's how they work and why they might be useful.
What are "biological aging clocks"? Think of a battery: New batteries start at 100% capacity, in terms of their ability to reliably hold a charge, but that capacity drops over time as the battery cycles on and off and powers devices. Biological age is a similar concept of capacity, and the tools researchers and clinicians use to measure your capacity are known as aging clocks, also known as "omic clocks" or "biological age tests."
Although such clocks are in development, the science of biological age is still in its infancy.

News from the world of politicized health.
Do what we say or you’ll die.
The environmental crazies have already declared me dead eight times...good think I have nine lives.
Lol.
>> “Biological age is notoriously hard to define because it’s very much a conceptual notion,”
Like gender, right?
And “he’s a biologist”!
“It’s not years, it’s the miles”.

The most important nutrient, program, system is................Attitude!
Besides longevity, a positive attitude, optimism, brings heath, and sometimes smiles. El Rush-Bo says that pessimism is easy. Optimism takes work.
A positive attitude overcomes many things. It overcomes most democRATS and DemoKKKrats.
According to my most recent physical a month ago, I am the equivalent of 67 "relative" years old.
Hmmm, doesn't seem like much science is involved there.
If one identifies as a female, will you live longer?
It uses a totally flawed formula that does not include a cubic factor, so it is not considering volume.
According to their BMIs, a tall, skinny person can be obese, while a short, fat person can be the shape of a pumpkin and the calculation says they aren't.
I’ve done quite well over the past 70+ years. It’s the weekends that have taken it’s toll.
According to my BMI and my wife I am obese..................
My frequent flier miles are adding up fast. I’M gaining on Methuselah.
My doc had a program where he’s put in information about me, weight, age, diabetes, blood pressure, former smoker, and the thing would tell me what my life expectancy would be.
I’ve outlived that, so I don’t think the thing was very reliable.
You’re only as old as the woman you feel....
God has an appointed time for us to die. An ‘aging clock’ won’t prolong what has already been set in time.
“An ‘aging clock’ won’t prolong what has already been set in time.”
You misunderstand.
An aging clock does not extend your life,
later
