Want to be 13 years younger (biologically)?

I spent $250,000 and gave 400 tubes of blood to crack the aging code.

Most people go about it all wrong.

I spent the money so you don't have to. Here's my exact longevity framework:

First, understand the key difference:

Chronological age = years since birth
Biological age = how old your body actually is at cellular level

Your biological age predicts disease risk far better than your birthday.

So why do most people ignore it?

OpenAI just spent $6.5B on iPhone creator Jony Ive.

Sam Altman calls their new AI device "the biggest thing we've ever done."

It could make your smartphone obsolete by 2025.

The technology they're building will change how you interact with AI forever:

First, let's appreciate this move's magnitude.

OpenAI spent $6.5B on a one-year-old company.

That's more than Google paid for Fitbit ($2.1B) and about what Facebook paid for Oculus ($3B) and Instagram ($1B) combined.

Why such a massive bet on an unproven concept?

Bryan Johnson spends $2M yearly to reverse his biological age.

I reverse-engineered his protocol for every budget:

$10,000/month (Millionaire)
$1,000/month (Professional)
$100/month (Beginner)

Here's how you can live forever on a normal salary:

Bryan Johnson turned himself into a human experiment with his $2M yearly "Blueprint" protocol.

He's reversed his biological age by 5.1 years, aging at just 0.69x normal rate.

What if you don't have millions?

Networking advice is mostly garbage.

"Just add value" and "be authentic" tells you nothing.

After 20+ years in tech, I've discovered what actually works:

The most accurate measure of your true age:

Oxygen efficiency.

Peter Attia confirms VO2 max correlates more with longevity than any other marker.

Here's why I'm determined to reach 50 by my 50th birthday (and the plan you can follow):

Forget your birthdate.

Your true age is defined by oxygen efficiency—measured by VO2 max.

This metric predicts longevity better than cholesterol, blood pressure, or BMI.

It's why Peter Attia calls it the most important health marker you've never heard of...

Our team spent months obsessing over design details.

When we launched, not a single user wanted them.

After 20 years at Microsoft & Instacart, here's the BRUTAL truth about innovation:

It sparked a revolution - millions dreamed of working less and living more.

• Outsource your life
• Travel the world

But here's what nobody tells you about the results:
