Can Kara Swisher show you how to live forever? — Terms of Service

[0:01] Welcome to Terms of Service. [0:03] I'm CNN tech reporter Claire Duffy. [0:06] Have you ever thought about what it might be like [0:07] to live forever? [0:09] Well, there's a growing group of people, [0:11] many of them in Silicon Valley, [0:13] who have been thinking a lot about that vision [0:15] over the past few years and trying to make it a reality. [0:19] The longevity movement has gained traction [0:21] and attention online with prominent boosters [0:24] advocating everything from good sleep and supplements [0:27] to experimental and sometimes extreme biohacking treatments. [0:31] Today, I am going to be joined by legendary tech journalist [0:34] and CNN contributor Kara Swisher, [0:36] who also hosts the podcasts On and Pivot. [0:39] She has spent the last few months [0:41] digging into the longevity space [0:43] and testing out treatments to figure out [0:45] what's real and what's snake oil. [0:47] If I had to say, everyone's like, [0:48] what's the number one hack of longevity? [0:50] I'm like, don't be poor, be rich. [0:52] Be rich, that will work. [0:54] She's also been interviewing people like Brian Johnson, [0:56] who has gotten a lot of attention [0:58] for his attempts to defy aging, [1:00] taking dozens of supplements every day, [1:03] religiously tracking even his most intimate bodily functions, [1:07] and at one point, even getting a plasma transfusion from his son. [1:11] All of that costs him around $2 million a year. [1:15] I'm saying that the primary thing that we want to do [1:18] is to say, like, let's just not die. [1:20] So why do you phrase it like that? [1:21] Because it is phrased and you market it, [1:23] and it's quite marketed, I want to live forever. [1:26] Oh, I don't. [1:27] So I specifically do not say I want to live forever. [1:30] Mm-hmm. [1:31] OK. [1:32] But you said you don't want to die. [1:34] Kara has a new documentary series airing on CNN and CNN All Access [1:39] called Kara Swisher Wants to Live Forever, [1:41] for which she was the host and an executive producer. [1:44] My conversation with Kara Swisher after this short break. [1:51] Well, Kara Swisher, thank you for being here. [1:53] Thank you for having me. [1:53] You're a beautiful place. [1:54] This is so lovely. [1:55] Oh, thank you. [1:56] So what drove you to investigate this space [2:00] and to try out so many of these longevity treatments for yourself? [2:03] You know, broadly, it's about tech, [2:04] which I've been covering since the dawn of time. [2:06] I've looked at social media. [2:07] I've looked at, you know, all manner of devices and stuff like that. [2:11] And the one area that tech has not been able to sort of unlock is health care. [2:15] And they've tried a number of things in terms of files and vaults and things like that. [2:20] But what I noticed was a lot of them were getting into funding all these health care companies, [2:24] but it was around living longer and longevity. [2:27] And the language sort of started to shift as they got wealthier and wealthier about living forever. [2:32] And so Larry Ellison started an anti-aging institute in Los Angeles. [2:36] There were investments by Sam Altman, Mark Zuckerberg, Jeff Bezos. [2:39] And they were really interested in it. [2:41] And a lot of the focus has been on rockets and stuff like that, [2:44] which is sort of a side version of let's go across the planet and live planets and live in another planet. [2:49] And so this idea of what they were trying to do, it was life extension, really. [2:53] And then there was, of course, Brian Johnson, who's made a son of a spectacle of himself for good or bad for him. [3:00] I don't know. We'll see in terms of trying to do everything and sort of monitor it. [3:05] And then the last thing is they love data and the human body is lots of things, but it's also a lot of data. [3:10] And so whether it's wearables or the Oura Ring or whatever it happens to be. [3:16] But a lot of the data is meaningless, really, and is not helping the broad group of Americans or anywhere across the globe. [3:23] How do you personally feel about death? Is it something that you think about? [3:26] I do think about it a lot. [3:28] My dad died when I was five, and so it has always been with me. [3:31] I had an encounter with it very early, and anyone who was like that does have that awareness. [3:37] And I then was further kind of inspired by Steve Jobs, who died young, youngish for him, [3:45] who gave a speech at Stanford talking about how death was his motivation in terms of creation and innovation. [3:51] And I think he was right. [3:52] And what it morphed into is I desperately don't want to die. [3:57] And FYI, everyone on this planet who's been here has. [4:01] Right. We're all going that way. [4:03] Everybody. [4:03] And so for some reason, we sort of try to avoid it. [4:06] And death avoidance is actually not very healthy. [4:09] Many world religions talk a lot about death acceptance. [4:11] And I'm not talking about obsession. [4:13] It's about talking about how you want to live, you know, in a lot of ways. [4:18] And instead, we try to pretend it's not happening. [4:21] And it is. [4:23] So give us sort of like the definition of what this longevity trend is. [4:27] It sounds like it's sort of an offshoot of the wellness trend that we've seen grow over the past few years. [4:31] Yes, the wellness trend is, and that's been sort of amplified and even weaponized by social media, right? [4:37] There's all these wellness grifters who are telling you things that are not true. [4:41] Either they're not true or they overstate them, but they're always trying to sell a product. [4:45] And, you know, people look at them and there's a great hope in humanity. [4:48] It's like, if I only had this elixir, you know, it's gone way back. [4:52] Ponce de Leon, fountain of youth, way back in Chinese dynasties. [4:57] They were always searching for the elixir. [4:59] Obviously, the vampire myths. [5:00] There's all, there's Frankenstein. [5:02] There's all manner of things that we tell ourselves in some way to cope with death, which is inevitable. [5:08] But it's, it's been all around us. [5:09] But now it's become amplified and sort of made into a product. [5:12] And they're selling health back to us. [5:14] How much of that is because the American health care system kind of sucks and people are looking [5:19] for some way to have control? [5:22] You don't see this as much elsewhere, right? [5:23] This idea of, look, we pay, I think it's now $15,000 a year per capita on health care. [5:30] And our outcomes are at the very bottom of every list, whether it's infant mortality, [5:35] whether it's obesity, whether it's length of life and everything else. [5:38] And so you're like, what are we getting for our money? [5:41] Very little and it's wasted and there's, there's a real sick care. [5:45] People talk about health care. [5:46] It's a sick care system where all of it gets piled at the end. [5:50] Unnecessary things that we do because we don't do preventative health. [5:54] The way we eat, you know, there's all manner of reasons why it is, [5:58] but we really do not value the health of our citizens. [6:00] And look, we can go on and on and guilt people into it, but it costs money. [6:04] Like, let's just, let's like focus on our greed. [6:06] Like we are wasting money in terms of being sick. [6:10] When we could do something very early on to mitigate what is inevitably going to happen. [6:14] And, you know, there's a lot said about health span versus lifespan. [6:18] The delta is so huge in this country. [6:21] Why is it so huge? [6:22] Why do we spend the last 10, 15 years of our life being sick? [6:26] Yeah, I thought that, that health span idea was so interesting from the show. [6:29] Yeah, it's been around for a while. [6:30] I do think, yeah, I think I, I know so many people who think about, [6:33] I want to exercise when I'm young so that I can be mobile when I'm older. [6:36] That's absolutely critical. [6:38] It is. [6:38] Then these guys take it to a completely different level. [6:41] Of course they do, because they can sell you a supplement. [6:43] They can sell you a vest. [6:44] They can sell, show you, oh, I have a program. [6:46] You know, every one of them always ends up with a program. [6:49] And look, I don't mind people making money off of their businesses, and that's fine. [6:53] I think what it is, is it plays into people's insecurities. [6:56] And, you know, oddly enough, men, like everyone's like, oh, women are so beauty conscious. [7:01] No, no, no. [7:02] Look online. [7:03] It's the men that are doing it. [7:04] I'm, you know, I have so many people come up to me. [7:07] I'm protein maxing. [7:08] I'm like, please stop, because what they're telling me is not accurate. [7:12] Right. [7:12] You mentioned some of the, some of the guys near the top, [7:15] but talk about some of the prominent figures in this space, especially Brian Johnson. [7:19] Yeah. [7:20] Who they are, and do they actually think that they are going to cheat death? [7:24] Do they really believe that? [7:25] No, he's played a lot of word games. [7:26] He has a, his whole motto is don't die, but he doesn't want to live forever. [7:30] I'm like, okay. [7:31] Okay. [7:31] He's talking about humanity, not dying. [7:33] I'm like, I think what he's talking about is he's desperately scared of dying, [7:37] and desperately scared of degrading. [7:39] And has, you know, he came to my conference before this all started, [7:42] and talked about brain health, and one of the motivators around brain health [7:46] was his own depression, which is a debilitating problem for a lot of people. [7:50] But then it morphed into this, which is obviously, I don't know, [7:53] no matter how you slice it, and he's aware of it too, and he says it. [7:57] He's like, I know people think I'm this narcissistic, [7:59] Patrick Bateman-style mother . [8:01] And I'm like, indeed, that's exactly what they think, or you're a vampire. [8:05] Right. [8:06] So he's aware of it. [8:06] And so much of it does feel like it's about the aesthetics. [8:09] Of course, and it's weird aesthetics. [8:11] It's like people who, like, obsessively do facelifts, [8:13] and then you're like, what are you doing to yourself? [8:16] And, of course, it's a journey of one, has no application to the rest of us. [8:21] He's like, oh, I'm putting opening source. [8:22] I go, what's going on with your pee has nothing to do with anybody else's pee. [8:26] And you need to do these gold standard studies around a lot of things with a lot of people, [8:32] and that's the problem. [8:33] It's a study of one. [8:35] So now we can know how Brian Johnson lives better, [8:37] but it has no application to Kara Swisher or you or anybody else. [8:41] How big is the longevity industry? [8:43] How much money are people making? [8:44] Huge billions, hundreds of billions. [8:45] It's getting bigger and bigger. [8:46] It's only growing. [8:47] Like, even just a small area, and I should have the numbers at my fingertips, [8:50] but like red light, huge growth. [8:53] Mm-hmm. [8:54] Not sure it works. [8:55] Uh-oh, they're selling blankets. [8:57] They're selling beds. [8:57] Everything from $60 to $70,000. [9:00] No science. [9:01] I mean, these people are going to come at me. [9:03] The red light people will come with red lights at me. [9:05] But there's some applications. [9:07] There's some possibilities of inflammation. [9:10] They certainly are experimenting with brain surgery. [9:13] Okay, let's look at it. [9:14] Let's figure it out. [9:15] What does work? [9:16] And I think that's what happens for centuries with diets. [9:19] You know, there's been like, oh, we must have mercury. [9:22] It's so good for you. [9:22] Oh, no, it isn't, right? [9:24] Right. [9:24] And so that's the thing is there's always been sort of a solution. [9:28] And, you know, at one point there was a countess in, I think, Romania [9:32] that would bathe in the blood of virgins to get younger. [9:35] I'm like... [9:36] Now people are injecting salmon sperm into their face. [9:37] That's right, or whatever it happens to be. [9:39] But it's against the backdrop of astonishing medical developments [9:43] that we should be paying attention to, whether it's GLP-1s, whether it's mRNA technology. [9:48] So politicized. [9:50] Such a shame what's happening here. [9:51] This is... [9:52] These are really astonishing things. [9:54] Gene editing. [9:54] How should we conduct it? [9:56] Eradicating diseases. [9:57] And so you have a lot of Silicon Valley people, one, talking about their own lives. [10:01] And at the same time, we're going to eradicate all diseases. [10:03] And I put my hand up. [10:04] I'm like, okay, how? [10:06] Where is it? [10:07] What's happening? [10:08] Tell us. [10:09] Let's know. [10:09] And so that's what I wanted to go on a journey to find, too. [10:11] For her documentary, Cara tested out a range of treatments promoted for wellness or longevity, [10:20] ranging from sound therapy and ketamine therapy, [10:23] to sitting in hyperbaric oxygen chambers and a red light bed, [10:26] and staying in a hotel room optimized for excellent sleep. [10:30] Some of it is okay. [10:32] Some of it's very expensive. [10:33] I mean, I think that's the knock on a lot of this stuff, [10:36] is that only rich people can afford it. [10:38] And some of it's kind of silly and maybe not very good for you, right? [10:42] That kind of stuff, or has very little effect. [10:44] And like one of them that I did was just a hyperbaric chamber. [10:48] Right. [10:48] And again, the hyperbaric chambers are going to come after me. [10:50] Oxygen, high pressure. [10:52] Well, if oxygen's good, double the oxygen is better. [10:56] Like, is it? [10:57] Mm-hmm. [10:57] It's not. [10:58] Like, you know, and so I feel better. [11:00] I've had, oh, I feel better after I come up from a trip. [11:02] I was like, okay, like... [11:04] Oh, yeah, the ketamine therapy. [11:06] Ketamine is another one. [11:07] Like, actually, there is incredible, interesting stuff happening. [11:11] We should do more studies about the good effects of psychedelic drugs [11:17] to replace SSRIs. [11:19] Great idea. [11:20] Let's figure out how to do it. [11:22] But let's have proof before we put clinics all over the country [11:25] that are not regulated. [11:27] The longevity industry isn't just pushing new supplements and gadgets. [11:31] There's also growing talk of extending our presence here on Earth [11:35] with the help of artificial intelligence. [11:37] Kara and I will talk about what that next frontier could mean for humanity. [11:41] And Kara will also offer her advice on what actually works [11:45] to live a longer, healthier life. [11:47] That's after the break. [11:51] So much of this seems to involve so much tracking. [11:54] Yes. [11:55] In a way that I'm like, does that not make you crazy? [11:58] Yes. [11:58] I think a lot of when wearables are called wearables a long time ago, [12:02] and I've tried them all. [12:02] I've been there since the dawn of time of wearables. [12:05] I call them unwearables. [12:06] I'm like, what's the, like, 10,000 steps. [12:09] Okay. [12:10] Which steps? [12:10] Where? [12:11] When? [12:11] Right? [12:12] That kind of stuff. [12:12] It never gives you information that's actual. [12:15] It just tells you the number. [12:16] And so one of the things that Silicon Valley especially is interested in [12:20] isn't just numbers, but what's the meaning of the numbers, right? [12:23] You can give me any number, but it doesn't matter. [12:25] And so I would like, if I was, this is just me, like, deciding to create something. [12:31] You have a wearable, like, if they want to embed it, embed it. [12:33] And it has a lot of information about you, and that's kind of interesting. [12:37] Okay. [12:37] You eat a donut. [12:38] It then says to you, oh, man, you just ate a donut. [12:41] Here's what you need to do. [12:42] You get up and walk right now because your blood sugar is spiking or whatever's happening, [12:47] and then get some celery immediately. [12:49] Whatever it is you need to get, it needs to tell you. [12:52] And then it explains to you, like, this is what the donut did to you. [12:55] And that would, in plain English, that would be really interesting, wouldn't it? [13:00] Or it feels indulgent, but actually it could be used across a population where it's like, [13:06] okay, you're doing this. [13:07] Here's what's in it. [13:09] Here's what's happening. [13:10] Here's what it does to you individually because everyone has their own individual [13:14] reaction to different things. [13:16] And that's another thing. [13:17] People get too much information and then start to take action. [13:20] Like, if you do a full body MRI, you know, oh, you have a polyp. [13:26] Oh, take it out, but it's a benign polyp. [13:28] Do not do surgery, right? [13:30] So once you start to know what is the usefulness of this information, [13:34] I'm not saying keep it from you, but knowing it could lead to things you don't want to have happen. [13:39] There's also this other way that people are talking about extending their life, [13:42] which is to make an AI replica of their personality, their, you know, your consciousness that could [13:49] live on after death. [13:51] Yeah. [13:51] What do you think about that trend? [13:53] It's nuts right now. [13:54] Yeah. [13:54] Now, what's interesting is there's just a story, Sam Altman wants to do this, like, [13:59] figure out what's it. [14:00] It's an idea of what the soul is, right? [14:02] Is there a soul? [14:03] They look at brains as if they're computers. [14:05] Computers wish they were like brains. [14:08] And so I think some of the stuff could be super promising and then they take it to that extreme. [14:13] And so I did an avatar and loaded it up with all manner of information. [14:19] And what's changed is they used to just tape people and then it would have stock answers [14:23] to whatever you taped. [14:25] Now it can have a discussion with you and then learns over time. [14:29] And it was interesting. [14:30] I'm probably going to have to kill it. [14:33] Did you feel like it was an accurate representation of you? [14:35] No, but it was. [14:37] You know, it's a facsimile. [14:38] Mm-hmm. [14:38] It's certainly a facsimile, but it's not the real thing. [14:41] The question is, would I want my great-grandchildren to meet that? [14:45] Maybe. [14:45] Hmm. [14:46] I don't know. [14:46] Would I? [14:47] Because it's not me. [14:48] And then it starts to become another version of me. [14:52] Right. [14:52] So then when it runs out of material, because I'm dead, what does it become? [14:58] It becomes another creature, right, or something. [15:01] But it was a really interesting discussion because I was like, well, what's wrong with me? [15:07] I said, first of all, you don't smile very much and you don't tell good jokes. [15:11] But by the end of the conversation, it told a pretty good joke. [15:14] Not great, but good. [15:16] And they said, why do you think I'm not you? [15:20] And I said, well, you lack empathy and you lack humanity and experience. [15:25] And what motivates you is an algorithm. [15:28] And the creature essentially said, yeah, my soul is the algorithm. [15:34] Well, it makes you wonder, would we stop valuing the time that we have with our real loved ones? [15:41] Because you're like, oh, I know I'll have this AI thing to interact with later. [15:43] Right, exactly. [15:44] I mean, you could imagine a cemetery in the future not being stoned, but little avatars that you just talk to these people. [15:49] But why not? [15:51] Yeah. [15:51] Like, why not have these 3D figures, holograms? [15:54] You know, you've seen Star Wars pop up and there you are. [15:58] And it's a facsimile of you. [16:01] And I really was fascinated by how quickly it learned. [16:04] It did. [16:05] You know, and it wasn't because it was sentient. [16:08] It was it was figuring and pattern matching and doing all manner of things. [16:13] And I have to tell you, it was a more interesting discussion that I've had with lots of people. [16:18] But we had a parting of the ways. [16:20] Throughout the series, you dig into the motivations of these people who are invested in longevity. [16:26] There's this point in the first episode where you play a clip of Jeff Bezos being interviewed on stage [16:30] and he's asked what he wants his legacy to be. [16:32] Yeah. [16:32] And he says, world's oldest man. [16:34] World's oldest man. [16:35] Cringe. [16:37] Jeff Bezos is a walking cringe. [16:39] Yeah. [16:40] And yet that is the thing. [16:41] Of course. [16:41] You've created this incredible business. [16:43] Right. [16:44] What did you learn from your reporting about what is behind this? [16:47] And what did they say in response to that critique? [16:49] I didn't interview Bezos, but, you know, I should have interviewed Larry Ellison because [16:53] he's the one that's been very much behind some of this and is doing some really significant, [16:56] interesting investments in this area. [16:59] But, you know, it's the old Carly Simon song. [17:01] You're so vain. [17:02] You probably think this song is about you. [17:05] That's the thing. [17:06] It's like so self-regarding. [17:08] And in some cases, they think they should go on because they're so special compared to the rest of us. [17:13] Mm-hmm. [17:13] I don't know what their motivation is, but it's certainly not. [17:15] If Jeff Bezos really cared about humanity or everybody else's length of life, maybe he'd act like his ex-wife. [17:23] Right. [17:23] She just gave $70 million to Meals on Wheels. [17:26] That's going to help. [17:26] Feed everybody, yes. [17:27] By the way, guess what? [17:28] That's a health outcome for people. [17:30] Mm-hmm. [17:30] She gives money where there are health outcomes to people in the now and in the here. [17:34] They are not thinking of that. [17:36] If he really cared, he might do something different. [17:39] Yeah. [17:40] Are there any longevity treatments that you found really work or that you've incorporated into your routine? [17:45] Yes, yes. [17:46] It depends on where you want to go. [17:47] Sleep, diet, you know, all those things are important. [17:49] I think interval training, for example, VO2 max, I found really interesting. [17:53] Obviously, for this woman I interviewed, GLP-1s were very good when combined with exercise. [17:59] I think taking your vaccines. [18:01] I'm sorry, people. [18:02] You're going to have to write me angry notes, but, you know, it's true. [18:06] I think some of the stuff, like fermented foods, that's a really important thing. [18:12] Not as much animal proteins. [18:14] I like a burger. [18:15] I do. [18:15] That's the way it is. [18:17] Not six of them a week kind of stuff. [18:19] Use the fine proteins in other ways. [18:21] That's food and diet and sleep. [18:23] Get enough sleep. [18:23] You don't have to obsess on it, but understand the importance of sleep for regeneration. [18:29] But really, it's very small things, and I think the most is friends and family. [18:34] That's really where the rubber hits the road. [18:37] And I interviewed just near here in Brooklyn. [18:40] I spent the evening with a brain scientist, a very well-known brain scientist, [18:43] and we played games with a bunch of 20-year-olds, and they put down their phones. [18:48] They played games with each other. [18:49] That's lovely. [18:50] First of all, they met people they didn't know, which is also good for brain cognition. [18:53] They play games, which is good for your brain. [18:56] They touch things, and they had interactions. [18:59] And she was explaining what was happening with cortisol and dopamine and everything else. [19:04] Interesting. [19:04] And it's all good. [19:05] It's everything about that was good. [19:07] The other day, I started to play mahjong because it's interesting, [19:11] and it's sort of on trend right now. [19:15] It's always been popular in certain parts of the world, [19:19] but it's now really sort of the pickleball of this year, I guess. [19:22] And I brought together 16 people, most of whom I knew them, but they didn't know each other. [19:28] The end of the evening, to a person, they're like, I feel better. [19:31] I'm like, you actually do. [19:33] Right. [19:34] It's not just because it's fun. [19:35] It's something else is happening here. [19:38] I interviewed Zeke Emanuel, who wrote Eat Your Ice Cream, [19:40] and one thing he does is different things because it's good for cognition, [19:44] and he learned to make honey. [19:46] He makes delicious honey. [19:47] He's a cancer specialist. [19:48] He learned to make honey. [19:49] He's doing ballroom dancing right now. [19:52] Anything that's different and unusual. [19:55] And then the last thing is death acceptance. [19:57] I interviewed a professor at Skidmore who's doing a study on death acceptance versus death fear, [20:02] and finding that the more you do accept it, the happier you are. [20:07] It has all kinds of knock-on effects, and happiness has a lot of knock-on effects on health. [20:14] And then I interviewed the head of the Harvard happiness study. [20:17] Same thing. [20:18] They have absolute proof that the people that live longer are social, [20:23] have social connections with other human beings, [20:25] not with bots or robots or whatever it happens to be. [20:28] Yeah. [20:28] Nothing. [20:29] I like a robot, but you know. [20:30] Right. [20:31] And it's amazing how much all of that is very low-tech things that we have known for a long time. [20:35] It is because you can't sell it to you. [20:37] You can't, they can't sell you today, you know, try to do Whole Foods. [20:41] And the last thing is I went to Korea, which is one of the longest living populations. [20:44] They've got lots of problems in Korea. [20:46] But one of the things they do have is women in Korea right now will be the longest living people [20:50] on the planet very soon. [20:51] Why is that? [20:52] There's lots of reasons. [20:53] Early nutrition stuff in schools. [20:55] We went to a school. [20:56] A lot of community stuff. [20:59] They have an aging population, so they're doing a lot of robotic stuff. [21:03] And I went to Robot Valley there. [21:04] And there's all this ectoskeleton stuff they're working on when combined with AI. [21:09] It's really interesting. [21:10] Could we, could people in wheelchairs, which is bad for your health, be able to walk? [21:16] Yes. [21:17] Like that's cool. [21:18] Yeah. [21:18] That's really interesting. [21:19] And that's really high tech. [21:21] So it's not that I don't like tech. [21:22] It's that how are we going to apply it for the broadest amount of people at the cost that will, [21:28] we're wasting money right now. [21:31] Absolutely. [21:32] Don't buy a red light thing. [21:34] Go see a friend. [21:34] Just don't. [21:35] Yeah. [21:35] I love that advice. [21:36] Don't buy a red light. [21:36] I'm not against red light. [21:37] There's some science in space with wound healing. [21:41] Hyperbaric chamber is another thing. [21:43] Like again, if you have the bends, go for it. [21:46] Absolutely. [21:47] Climb yourself into that hyperbaric chamber. [21:50] If you have wounds, good idea. [21:52] It's just a question of taking something and then applying it in ways that just don't have [21:57] provable benefits. [21:59] Well, Kara Swisher, thank you so much for doing this. [22:01] Thanks very much. [22:02] I really appreciate it. [22:02] I hope you live long and prosper. [22:03] Thank you. [22:04] You too. [22:09] No one has yet figured out how to cheat death, and there's currently no indication they will [22:15] anytime soon. [22:16] But it's normal to want to live a long and healthy life. [22:19] And as Kara said, acknowledging death can actually make you appreciate the time you have [22:24] even more. [22:26] Despite the recent uptake in interest and investment in longevity from Silicon Valley, [22:30] the proven methods of extending your life and improving your health are pretty low tech. [22:36] Things like eating a balanced diet, sleeping well, exercising regularly, [22:40] challenging your brain by learning new things, and prioritizing time spent with loved ones. [22:46] If you have extra cash to spend and want to try out one of the trendier longevity practices, [22:51] like red light or hyperbaric oxygen therapy, go for it. [22:55] Even just the practice of relaxing and disconnecting from screens for a bit could help you feel good. [23:00] Kara says some of these tools could have useful medical applications in certain contexts, [23:06] although they need more robust testing. [23:08] But keep in mind that seemingly too-good-to-be-true fixes peddled online are often done so with profit in [23:14] mind, not your health. [23:17] And make sure to talk to your doctor about any new treatments you're trying. [23:20] Kara's documentary series is called Kara Swisher Wants to Live Forever. [23:25] Episodes air on Saturdays at 9pm, or you can stream them on CNN All Access. [23:30] That's it for this week's episode of Terms of Service. [23:33] I'm Claire Duffy. Talk to you next week.
