If you don't like someone, don't turn them on to because you will live literally forever. Even NASA uses it and has been studying it for 50 years. There's no other place you can get this. There's 25,000 studies proving that superoxidism mutase prevents Alzheimer's, heart disease, inflammation, but nobody knows that you can get the highest concentration of it in and our bodies reduce the production of that after 30 And so by the time you're 40 or 50, you have less of it.

You should listen to Catharine because in a month, she turns 70 and she's got a brain that's completely working, almost like this doing something. And our expectation is that when people hit around 70, that we should be grasping for words and we should be tired. And that's not what aging looks like.

The Hippocrates Institute, which is a wellness center in Florida, West Palm Beach, they take cancer patients who are given a couple of weeks to live. And one of the first things they do is they give them because it has all these nutrients that bring their mitochondria and their cells back to life.

All cause of mortality goes out when mitochondrial function goes out. Aging goes down when mitochondrial function goes out.

Catharine Arnston (0:59)

Aging is natural, declining is not. And I want to be an example for people. Just because you see people that are decrepit and foggy and tired and not being able to think, that's not natural. That's what we see. That's our baseline. But I want to show there's another baseline.

Have you hit your protein goal today? Well, you might, but it's probably not good protein. And ButcherBox has made it easier to get good protein for your protein goal. They deliver 100% grass-fed beef and organic chicken and wild-caught seafood and a bunch of other good stuff right to your door. They've already done the research and they made the tough sourcing decisions. So you don't have to go to the store and ask questions that the butcher can't answer anyway. That means all you have to do is decide what's for dinner. Every ButcherBox is customizable. So you can choose the cuts and the proteins that fit your routine and just what you like to eat. Busy weeknight or friends coming over? You've already got great protein ready to cook. My days are really busy, so it's easy to just throw one of their grass-fed steaks on the grill after I work out. And if you're looking for an easier way to make great meals, give ButcherBox a try. Go to butcherbox.com/humanupgrade to get $20 off your first box plus your choice of free ribeye, New York strip or filet mignon in every box for a year with free shipping always. Again, that's butcherbox.com/humanupgrade.

Be sure to use our link so they know we sent you. Why won't your stress budge no matter what you do? You're doing the work, the cold plunge, the breath work, the supplements, and your nervous system is still running hot. Here's the problem. Every recovery tool you use only works when your body believes the threat is over. And if your nervous system never gets that signal, it stays in survival mode regardless of what you stack on top of it. The direct line to that signal runs through your Vegas nerve. When you stimulate it, your parasympathetic nervous system activates. Your body shifts out of fight or flight and into the state where real recovery happens. ZenBud is the tool I reach for to make that shift happen. It sits on your ears like a headset and uses focused ultrasound to reach your Vegas nerve directly. Just five minutes daily is all you need. In clinical studies, participants experienced significant improvements across stress, mood and sleep after just four weeks of use. Many people notice it in their first session. Check it out at ZenBud.health and use code DAVE15 at checkout for a discount. Your biohacks are only as good as your nervous system's ability to recover. This is the missing piece.

What would happen if you spent more than 20 years obsessively focused on just one thing, algae?

Now, you might think that you'd end up with something. You ever see that movie, The Swamp Thing from the 80s? There's this guy, I just love plants and he becomes a plant. Then he defeats all the other bad mutants. This is actually the real life longevity version of that movie. Catharine Arnston has a PhD, recently acquired one, an MBA, and is a board certified health coach. She's done 300 plus podcasts, but she's literally merged her being with algae.
