You had lunch, and I've always wondered why they put our session in the afternoon. Because science has clearly shown that after a meal, all the oxygen leaves the brain. And you guys go and take a nap. It's sort of interesting. Some of you have come back by the way. Listening to this morning is really interesting. Some of you have been to Malawi, right? Yes. And I think there's another way after this you'll be going to Malawi as well. Okay, you might have missed something. Let me tell you a story because at the very beginning when we created this so-called Vitameal project to support all the kids that are having really good food, the phrase 'nourish the children' was deliberately chosen. You notice we never say 'feed the children.' It's always 'nourish.' And that's what makes our program very different from all the federal programs, WHO programs, and all that. All the programs around have always been 'let's feed them wheat, let's feed them corn, let's feed them rice.' There's no nourishment. It's all carbs. Our Vitameal was designed to be a complete meal. It was designed in collaboration with a WHO pediatrician at UC Davis. So when we talk about what we do at Nu Skin, even though it's 5% of what we do or whatever it is, it's 95% of who we are. That's really true because we always say we're innovative. We don't just stop innovating just because we want to create a meal. That was an innovative product. That's the difference, perhaps, than anything else. The word innovation for us, it extends and permeates everything that we do. So today I'm going to take you through a little bit of a journey, if you will: the past, the present, and the future. And because Yoko showed you a whole list, a scrolling list of products we have produced and developed over the years, to the extent that some of you may feel there's so many products, why do we actually are able to consume or actually be able to understand all those products? So I'll give you an umbrella because fundamentally what we are, when you look at all the things that we do, we're an anti-aging company. No more, no less. Whatever we do, that's the umbrella that we exist under. Guys, it's anti-aging. There's nothing to be confused about. You don't need to ruminate. When we bring on a new product, and in the future too, it will always be Nu Skin as an anti-aging company. You may not like it sometimes, some of you if you're young, for example. But just tweak the word and you can talk about youth preservation. It's the same thing. Our products are applicable at any age group. Anti-aging is not just for old people. It's for everybody. But nonetheless, that's the word that we use and that's the word we'll always be. This is the umbrella that we have. Yoko has given you a little bit of the history behind what we did. So when I first came into the world of Nu Skin back in 1998, what did I see? It was like I was a new distributor. I didn't know anything about Nu Skin. After the acquisition of Pharmanex, what did I see? There was only one tagline. There was only one concept. It's always about 'all of the good, none of the bad.' And it applies to the products and applies to everything. It's about even back then in 1984, more than 40 years ago, it was about anti-aging. So as we progressed in our science and innovation in Nu Skin product development, it has always been that. Then Pharmanex came in. What did we do? We just added more scientific evidence to make and buttress the initial concept of 'all the good, none of the bad.' We brought out the BioPhotonic Scanner. What did we say? We said it measures antioxidant. I'm going to take you through what we have done through the advent of AI and through the 20 years that we have been gathering data on the scanner. We have made that into a translator. It's no longer just an antioxidant scanner. And that's why, in fact, it's probably one of the reasons why I'm still back here, because it's so exciting that we are able to transform that particular device into something even deeper and more profound. So you just go through the whole thing. That's what we have. They can always be accommodated under the anti-aging umbrella, no doubt about that. So we'll talk about healthy aging in general. I just want to show you schematically, as you go through and a supplement, it's absolutely right. But the science tells us that this supplement that you're moving people over using a Prism scale over to a healthier level. And to give you a hint, it's because of the Prism. That is beginning to show us that the scale that we have created is not sufficient to cover the power of the observation that we get out of Prism. There is another level that all of us can reach for that will bring us even healthier aging. That's the key. By the way, when I go back to the original scanner, one of the biggest criticisms that we ever received from our competitors is, 'Oh yeah, they have that little scanner thing. Oh, that's Nu Skin made because they wouldn't make LifePak look good.' Okay? It's a LifePak detector in a way. They have a little leprechaun sitting inside staring through their probe, and when they see a competitive person coming through, they turn the scanner number down. Many variations of that. We had LifePak, guys. I mean, historically, we had LifePak before we had a scanner. When the company wanted to commercialize the scanner, I was sweating bullets that we could actually use that to show that LifePak is a very meaningful supplement. The average supporter, however, none of the guys in the room were sweating bullets. Now, what we've done for the last 20 years, we have actually flipped it. Prism helped to improve LifePak. And all of you, I bet you missed the most important improvement. And the product, we don't even spend time to talk about it. That LifePak that Yoko showed on a couple of slides, that is the new LifePak. That new LifePak was developed with the help of the Prism. We flipped it because of the data that we have. So that's what Yoko showed us. The scale is going to be a little bit larger.

This book was the bane of my existence because one day Ryan walked into the office and said, 'Joe, you've got to go write a book.' I said, 'You go write a book.' He said, 'What do you want me to do?' I said, 'We need to write a book. We have so much science and we're launching a new product. The ageLOC science has improved and progressed to another level. Why don't you go write another book?' The first book I read, it was actually quite interesting. So he said, 'What?' I said, 'Really? Does that mean I can't go fishing?' He said, 'Yeah, yeah, whatever.' So it took me some time to accept it. A few months to think, 'Really, I have to write? Oh gosh, yeah. Ping will kill me.' So anyway, we started. I said, 'But how do you get this book done?' And I said, 'Well, if there is a need, I don't disagree. We have launched a few products.' I said, 'It might also be good to include the science behind those products too.' So I added a few chapters to the previous edition and made it a new edition. But it's important. Chapter 10 is shown here, and it's the last chapter. Ryan alluded to that in the morning because it describes all the devices that we have introduced in the world of Nu Skin. And Prism had a prominent place in that chapter because it explains how it became a translator rather than just an antioxidant scanner. It's transformative, guys. It's not an incremental improvement to the scanner. Whether you like it or not, okay? Whether you say, 'I don't know how to incorporate it into my business,' fine. But fundamentally, this has changed the face of aging. And you've seen all the data that Yoko showed you. It's a huge market opportunity. We've got to find a way to incorporate this because if you truly think you're a force for good, and I'll switch over to that side, and you don't use the Prism, I think you may have a harder time. This is introducing a new type of science which I will call at this time behavioral nutrition. You can see the science. You can do the science now. It's not just me standing up there trying to explain all the science to you. It's rather arcane. Now you have in your hands a device, a precision device if you will, that can actually demonstrate making the invisible visible. It's a category creator. And you're going to hear a lot from everywhere. 'Oh, we're going to measure all kinds of biomarkers from the blood, and we will tell you how healthy you are or how unhealthy you are.' I don't think I want to get into that race because it would be a hamster in a wheel. There are so many biomarkers in the blood. Plus, really? Seriously? Nu Skin is going to have each and every one of you go around poking people on their arms and getting blood? Really? You guys don't even read the instruction manual on the Prism. And I'm going to get all of you to poke people? No. Those are the biomarkers, but the problem is when you get into that arms race, you'll never win. You just keep going. But with Prism, it's non-invasive, 15 seconds, you get a real-time reading on how you age or how you are nutritionally, the status of your nutritional health. It's a precision device. I want you to remember that. When we launched the Prism, I know you guys are going to come and whine about the variability. When it went out, we scientists knew there's something in there with the Prism light technology that we are picking up, but we don't know what it is. And all of you will perceive it as noise. And you're going to say, 'Gee, something like at 350, something like at 400, what's wrong with your Prism device?' No, there's nothing wrong with the Prism device. It's everything that's wrong with you. Because we've never been able to articulate that noise is actually ET trying to call home. We are just at that level where we are able to decipher what that noise is. So that's why we have the Prism. And the global scan, as you can see, we are all moving towards the left. Not good. You should be all towards the right. So globally, this supports what Yoko is saying. There is a huge opportunity for all of you because everybody needs an improvement in their nutritional status. Yoko has shown you this. I grouped them into two groups. One is the fact that if you do more of those things on the left, you're going to improve your nutritional health. And this is my first intro now. He said, 'Never use the word antioxidant. Never use the word carotenoid.' Every one of you, I'm so impressed all of you guys can actually pronounce carotenoid. It took me a few years to learn how to pronounce that word. So it's a nutritional monitor. When you do more of the things on the left, your nutritional status goes up. But on the other side, you need to do less. BMI always relates to weight management. The lower your BMI, the better your score. Many of those things are lifestyle factors, external factors affecting your body. And it's changing something. I want to take you to the future because that is a great indicator of certain things that are happening. The present is such an exciting tool that even universities have shown. We have mentioned some names previously, Jiang Tong from China, Young-Sai from Korea, and so on. There's a little university up the road in Palo Alto. We'll name it because they're not as good as the one on the East Coast, but nonetheless, we had a collaboration going with them. This is what it showed. This is interesting. It relates to what Joe Boy alluded to: health span. Really, health span is about quality of life, nothing more, nothing less. Those 10 years that Yoko showed you represent quality of life. That's what we're really interested in. It's not how you live longer, it's how you can live younger, longer. One word makes all the difference. So we did this study and we said, 'Look, you guys are so good. Dr. Chen, Dr. Annie Chen, no relationship, go and take our Prism and do a study among people, and at the same time, give us some skin tissue and blood.' Doctors can do that, by the way. Skin doctors are fascinated by fashion. They take biopsies of skin without telling you. It's okay. When we got the samples, we sent them to a gene lab we have been collaborating with and asked them to show us what genetic changes they could see in all these samples. The samples were blinded. The genetics lab didn't know where the samples were coming from. They showed us really interesting data. This is where ageLOC came into play and opened our eyes, giving us incredible insight: there are epigenetic changes. 'Epi' is a Greek word meaning things on the surface of the gene, on the DNA strand, which you can change. When you have an analysis from Ancestry or 23andMe, they look for genetic physical defects. Those things are immutable. You have it. Nothing can change it except gene therapy. But epigenetic changes are controlled by the environment, like lifestyle factors. What they were able to show is that the higher your Prism score, the younger you are in terms of biological aging. Every single tissue, more than 11 tissues, age. I tend to put brain fairly high because that's the first thing that goes with aging. So what have we done? Another translation. The Prism tells me in 15 seconds what your biological age is. The Prism device separated biological aging from chronological aging. If you are 70 years old, you don't need to be 70. You can be at least 65 years younger in terms of some tissues. That's the transformation, guys. With the Prism. It's an incredible tool, a non-invasive tool that all of you have in your hands, and you are able to explain and describe what's happening to an individual. On average, it's about four years. That's pretty significant. Yoko has already shown you the number one thing that can improve the Prism score is supplementation. Here you go: ageLOC. We have a device, antioxidant. Now we have Prism. And you have a transformation to nutritional health, which we launched the Prism as a path to healthy aging. Everybody talks about biological age, but nobody has been able to show it in a visible manner. You have. These are just some of the universities we are collaborating with, and there's more data to come. The reason these data are becoming more meaningful is because we have the original scanner that we had for 20 years with a huge database. No other company can say 'we're measuring antioxidants' but can't translate because they don't have the database. That's proprietary. That's why Joe Zembra is getting excited too. AI doesn't operate if you don't have data.

I'll come back to variability a little bit. The Prism is not like Kaboodles. Many of my Asian friends will know what they are, but the rest of you know them as pop marks. You buy that thing, you open the box, you get whatever color, and then you hang it on your backpack. It's a fashion statement. You shouldn't do that with the Prism. I've seen some of the variations that come back. There is some variation that I will share with you. Under controlled scientific environment, I can show that this variation is fairly tight. But if you abuse the Prism, it's not going to behave. I've seen Ryan pulling the Prism out of his pocket and immediately putting it on his left hand and scanning. Well, you can't tell the CEO not to do that. He's setting a bad example. When we launched it, you had some instructions, but as soon as you were so excited, you threw the manual away, didn't you? None of you ever read the manual that came with it. I never did. I bet you didn't with the Prism either. And then you whine about the variation. All things considered, I'm going to tell you that every single measuring device, all the way back to the blood pressure cuff, has variation. There's 7% variation with a blood pressure cuff. You like the ring that lights up when you put it on your finger? You just look at it. That has up to 40% variation. Go complain to the Aura manufacturer. You never did. You just say, 'Oh, it's okay.' So ours under controlled environment is about 5 to 8%. And I'm beginning to understand, thanks to all of you, that when you send in the data with the Prism, we plotted it. This is what we have. When you are below 500, you're tightly aggregated together. This is fascinating. You can drop it off and say, 'We did a regression analysis,' and people will understand what you're talking about. They were very tightly together. The problem is as you score higher, there is more scatter. And that is affecting our algorithm. That fancy equation at the top is the algorithm we use to drive the AI in our Prism calculation to generate a score. We are adjusting that. We are beginning to realize that when you hit a high number and when you are from a certain region of the world, the equation has to be adjusted. That's what we're doing. The first step you're going to get is the higher score, the platinum region. That will be launched very shortly. It will bring it up to about 1,200. Then there will be following on once we finish the analysis in each region; we can adjust the equation. So that's why we are adjusting that.

I think I'll end on this noise thing that I started off with. Think about your radio. I hope my audience at the back will help me out on this one. I'm asking them to tune to a particular station here in Johannesburg. It's a station that all of you ought to understand. Can you play the first station? [Audio plays: English.] You got it, right? English. Each and every one of you would understand what it is. Can you give me the second station? [Music plays.] That's an African tribal language. None of us would understand that. I'll give you one more, sort of based on a Western language. Give me the third station. But please don't get too excited. [Audio plays: Afrikaans.] That's African because it was based originally on the Dutch language, but none of us understand that either. Three languages almost say the same thing, but only one. That's what the Prism is. The noise is actually a language. The language is related to some really exciting new molecules or substances that we are picking up from the body, indicative of another aspect of healthy aging. So watch this space. Next time, maybe we will be able to tell you what we are measuring in addition to the carotenoid. I'll give you another analogy. English: Prism, everybody understands. Prisma, maybe I can figure out, but definitely in Zulu, you wouldn't be able to understand that word because that also means Prism. But nonetheless, I would consider the bottom two to be the type of noise that we have to decipher and convert to a language. It's not noise. It's information. We just don't have the ability right now to do it. So what does that tell you? That's the future of Prism technology. The platform is broad. It's profoundly indicative and predictive as we go forward. And nobody has that.
