How Fast Are You Aging? Your Speed of Aging, Free

Updated 5/31/2026 · 3 min read

"Speed of aging" went mainstream when Bryan Johnson's Blueprint and Netflix's "Don't Die" put pace-of-aging clocks (like DunedinPACE) in front of millions.

Those clocks use a DNA test that costs hundreds of dollars. You can get a free, instant estimate of the same idea — are you aging faster or slower than your peers — from your habits.

What 'speed of aging' actually means

Pace-of-aging asks: for every calendar year, how many 'biological years' is your body racking up? Faster than 1.0 means you're aging quicker than average; slower than 1.0 means you're banking time.

FINITE estimates the same direction from lifestyle and (optionally) standard blood markers — no DNA kit required. It's an estimate, not a lab clock, and it's honest about that.

The free, democratized version

You don't need a $2M protocol to get the signal that matters: which of your habits is speeding the clock, and which one change slows it most. That's what a free tool can give you today.

Think of FINITE as the mass-market version of the biological-age test the longevity crowd pays for — minus the cost, the blood draw, and the hype.

How to slow your clock

The unglamorous truth from the data: not smoking, moving most days, eating mostly real food, sleeping 7–8 hours, and going easy on alcohol do most of the work — long before any supplement.

Run the simulation, find your single biggest lever, and pull that one first.

FAQ

How can I measure my speed of aging for free?

FINITE estimates whether you're aging faster or slower than your peers from your habits, in about two minutes, with no signup. A blood-based version is also available.

Is this as accurate as Bryan Johnson's test?

No — epigenetic clocks like DunedinPACE use DNA and are more precise. FINITE is a free, instant estimate of the same direction. It's a mirror, not a lab result.

Can you really slow aging?

Habits like quitting smoking, exercise, better diet and sleep are associated with slower aging and longer healthy life in large studies. The simulator shows how each change affects your clock.
