Your Birthday Is Not Your Real Age
Chronological age is fixed. Biological age is a choice. Learn how to slow down the clock inside your cells.

InnerAge measures the wear and tear on your internal system, giving you a single metric to track and improve over time.
There's a person you know who's 50 but looks 35. And another who's 35 but looks 50.
Same chronological age. Completely different biological age.
One of them is aging fast. The other is aging slow.
And the scary part? You probably don't know which category you're in.
Chronological Age vs. Biological Age
Your birthday is just a number. It's how long you've been alive.
But biological age is different. It's how fast your cells are aging.
Your cells age based on your habits. Your food. Your sleep. Your stress. Your movement. Everything you do either speeds up or slows down your cellular aging.
Two people born on the same day can have completely different biological ages based on how they've lived.
What Actually Ages Your Cells?
Three main things accelerate biological aging:
Chronic inflammation (measured by markers like hs-CRP). Unstable blood sugar (measured by glucose and HbA1c). Hormonal imbalance (cortisol, testosterone, etc.).
If these three things are running high, your cells are essentially in a state of constant stress. They're breaking down faster. You're aging faster.
Even if you feel okay, your cells might be aging at 1.5x the normal rate.
The Invisible Acceleration
Here's what's terrifying: you can't feel it.
You can't feel your inflammation rising. You can't feel your glucose spiking after meals. You can't feel your cortisol staying elevated all day.
But your cells feel it. They're aging.
You only realize it five years later when you look in the mirror and think, "When did that happen?"
The Good News
Biological age can be reversed. Unlike your birthday, it's not fixed.
If you lower your inflammation. If you stabilize your blood sugar. If you manage your stress. Your cells slow down their aging.
You can get younger at the cellular level.
But you have to know what you're targeting.
How to Find Your Biological Age
This is the piece most people never do: calculate your actual biological age.
You can't just guess. You need data.
InsideTracker uses a sophisticated algorithm that analyzes 13–17 key biomarkers (like glucose, hs-CRP, and liver enzymes) to calculate your exact InnerAge.
It might be higher than your birthday. It might be lower. But now you have a target.
The Experiment
Over the next 90 days, focus on the three big inflammation drivers:
Sleep. Eat mostly whole foods. Move your body. Manage stress.
Get retested. See if your biological age dropped.
If it did, you now have proof that your actions are actually working. You're getting younger at the cellular level.
That's a game-changer psychologically and physiologically.
Going Deeper
The challenge is: you won't know your actual biological age without comprehensive testing. And you won't know which of your habits is actually moving the needle without seeing your markers.
InsideTracker calculates your InnerAge and tracks how it changes over time. It shows you which biomarkers are driving your aging and which lifestyle changes actually improve them.
It turns "getting younger" from a vague goal into a measurable, trackable number.
