Today, we're going to learn about "zombie cells" and how they affect aging. Plus, we'll explore what scientists are doing to tackle this intriguing issue.

There's a bunch of wealthy entrepreneurs who are really curious about uncovering the secrets of anti-aging and they are spending millions on research trying to crack the code of living forever.

Sam Altman, the CEO of OpenAI, is quite the health enthusiast. He's a vegetarian, hits the gym regularly, and takes metformin, a cheap diabetes drug that has been co-opted by biohackers hoping to extend their lifespan.

Metformin is among a class of drugs called "senomorphics," pills that are showing promise in taming aging cells known as "zombie cells."

So, what are these "zombie cells"?

Zombie cells, scientifically known as "senescent cells," are a special type of cell that has stopped dividing and multiplying. They're like the retired rock stars of the cellular world, chilling out and enjoying retirement. However, here's where it gets interesting: even though they've hung up their division boots, they're still active and kicking. These sneaky cells release molecules that can cause inflammation, which can be a bit of a bother as we age.

Now, before we go pointing fingers at these zombie cells, it's worth mentioning that they aren't inherently bad. In fact, some senescent cells play crucial roles in our bodies, like acting as defense mechanisms against cancer or helping with wound healing. They're like the wise old sages of the cellular realm, imparting their knowledge and lending a helping hand when needed.

But here's the catch: as we grow older, these zombie cells can accumulate and start causing some mischief. Their secretions can contribute to a whole host of age-related diseases, like heart disease, Alzheimer's, arthritis, and others. So, scientists have been on a mission to find ways to deal with these troublemakers. They've long been a target of researchers who believe that eliminating them — in very targeted ways — could be a new way to slow down aging.

Besides repurposing drugs like metformin, scientists are also cooking up new drug combinations called "senolytics." These combos aim to flush those zombie cells right out of our bodies, like a good ol' detox.

But let's take a moment to ponder this. Imagine a world where we can all pop a pill and watch the years melt away. No more worrying about wrinkles, creaky joints, or forgetting where you put your car keys. Sounds like a dream come true, right? Well, before we get too carried away, let's remember that the pursuit of eternal youth has been a human obsession since... well, forever. We've had everything from miracle elixirs to mythical fountains, and now we have tech moguls investing their billions in anti-aging research.

Dr. James Kirkland, an anti-aging zombie cell researcher at the Mayo Clinic, has been busy experimenting with a cancer drug called dasatinib and a plant compound called quercetin. And the results in mice have been impressive. Longer, healthier lives for those little critters! And even in some small-scale human trials, folks with age-related lung issues who tried the combo over a period of three weeks could walk faster and get up out of a chair more easily at the end of the study period.

But hey, we're not quite at the "take these pills and live forever" stage just yet. More testing is needed to ensure safety for everyone, and these drugs aren't meant for everyday use or prevention just yet. Dr. Kirkland is quick to remind us that these drugs are no walk in the park.

"These drugs aren't something the general public should be taking," Kirkland said. "They're not meant for prevention. What we're using them for is in very serious conditions."

He's hopeful that "over the next five years, some of these things may work for some conditions," like untreatable cancers, including glioblastoma.

For the rest of us, Kirkland says "things like exercise and dieting can reduce senescent cell burden as well."

Now, I don't know about you, but the idea of taking a pill to keep me spry and full of energy sounds enticing. But let's not forget that aging is a natural part of life, and there's beauty in embracing every stage of our journey. So, let's keep an eye on these tech titans and their ventures into the world of anti-aging. Who knows what they'll discover and how it might shape our future? But in the meantime, let's embrace the laughter lines, the silver strands, and the wisdom that comes with the passage of time. After all, life is one grand adventure, wrinkles and all!
