Episode notes

We have always thought that aging was an inevitable fact of life—but what if it wasn’t? What if we could actually prevent it… one test at a time?

This is exactly what I discuss in this week’s episode of The Dr. Joy Kong Podcast with my guest, the brilliant Alina Su.

Alina is a pioneer in the world of longevity science and the co-founder of Generation Lab, a biotech company at the forefront of reversing biological age.

Alina and her team are completely rewriting the rules of aging. With cutting-edge tools that go far beyond outdated biological age clocks, they’re helping people understand not just how old they are biologically—but why. And more importantly, what they can do about it.

In this episode, Alina and I discuss why most biological tests don’t work, the concept of “biological noise”, and how plasma dilution is revolutionizing longevity science.

She and I also talk about how your body ages by organ system, why “young blood” isn't the miracle cure it’s made out to be, and how random gene expression could be the real villain behind aging.
