Key Discussion Points and Insights

The Human Obsession with Immortality

• Historical roots:
  Venki begins by referencing the pharaohs of Egypt as emblematic of humanity’s deep-seated efforts to evade death.
  • “Humans try to avoid death by a variety of strategies. Plan A is simply to try not to die. Plan B is to try to believe that even if you die, your whole body will be resurrected… Plan C is that maybe your body will decay, but you will have an immortal soul…” (Venki, 01:03)
• Modern context:
  The pursuit of longevity is now a multi-billion-dollar industry, full of hype and bold claims, especially among tech elites.

The Science: What Determines Our Lifespan?

• No fixed upper limit but practical barriers:
  While there’s no physical law capping human lifespan, practical and biological limitations abound.
  • “There’s no physical or chemical law saying that our lifespan has to be what it is today.... But saying there's no physical law doesn't mean anything… I put this long life extension hundreds of years in that category, which is highly unrealistic today, despite what you may hear from various people promoting [it].” (Venki, 01:42)
• Aging at the cellular level:
  • DNA and molecular damage accumulates despite sophisticated repair mechanisms.
  • Processes like cell senescence (where damaged cells stop working properly and may cause inflammation) serve as cancer prevention early in life but contribute to aging over time.
    • “Just the act of living causes damage, but we have sophisticated repair mechanisms… But at some point the damage starts accumulating with age. Those mechanisms are never perfect.” (Venki, 03:44)

Hype vs. Reality: The Role of Tech and AI

• AI’s promise and limitations:
  Venki is skeptical of bold predictions that AI will soon eliminate all illnesses.
  • “He [Demis Hassabis] predicts that within 10 to 15 years there won’t be any illnesses left... I think maybe he's being a bit over optimistic.... The world is not digital. The world is analog. And I think they simply don't want to confront that.” (Venki, 04:54; 05:55)
• Tech industry’s bias:
  Tech leaders often see biology as a software problem—an outlook at odds with the messy realities of biology and drug development.

Money and Motivation in Longevity Research

• Societal need:
  Ageing populations create economic and social pressures; research focuses not just on longer life, but on extending “healthspan” (healthy years).
  • “The goal of this is…to make your life as healthy as possible… not necessarily extending life, but…increasing health span rather than lifespan.” (Venki, 06:25)
• Ego and escapism:
  Many large-scale funders are wealthy, middle-aged men with a strong drive for control and fear of mortality.
  • “There is a group of people who just have these grandiose visions... they simply think that everything is just going to go their way. And these people don’t want to die.” (Venki, 06:25)
  • “They’re all middle aged men, often married to younger women, by the way, which is a strong incentive to want to live longer.” (Venki, 08:03)

Practical Advice for a Healthier Life

• Caloric restriction:
  • Pathways linked to eating less may slow aging, but severe restriction isn’t sustainable.
    • “People on a truly caloric restricted diet, they’re hungry all the time.” (Venki, 08:38)
    • “You can eat moderately and you can try to not be obese…GLP1 drugs have now shown all kinds of effects…they might make old age healthier.” (Venki, 08:49; 09:11)
• Attitude and well-being:
  Living gratefully is valuable, but Ramakrishnan doubts a direct link to longevity.
  • “Some things you do because they’re worth doing… not just because… it’s about enjoying life while you have it.” (Venki, 09:24)

Facing Mortality

• Personal reflections:
  Venki discusses the recent deaths of close family members and expresses hope to face his own mortality with reason and equanimity.
  • “I hope… when my time comes… I’ll face it with the same kind of… equanimity or rationality that… I saw in these [family members].” (Venki, 09:44)

Notable Quotes and Memorable Moments

• On the allure of immortality:
  “When they were young, they wanted to become rich, and when they are rich, they want to become young.” (Nicolai Tangen, 00:00)

• On grandiosity in Silicon Valley:
  “They solved the problem of payment transactions, so we should be able to solve death.” (Venki, paraphrasing, 08:00)

• On embracing life rather than fearing death:
  “Everything is not about living longer, it’s about enjoying life while you have it, right.” (Venki, 09:24)

Transcript

[A]

Hi, everybody. Tune in to this short version of the podcast, which we do every Friday. For the long version, tune in on Wednesdays. Hi, everybody, and welcome to In Good Company. I'm Nicolai Tangen, the CEO of the Norwegian Sovereign wealth fund. Now, longevity is one of the hottest topics in the world right now. Billionaires are pouring money into it. You know, when they were young, they wanted to become rich, and when they are rich, they want to become young. The wellness industry is selling it and opinions about how to live longer and everywhere. So we wanted to find out what is real, what is hype, and how close are we to live forever. To help us answer this, I'm joined by Sir Venki Ramakrishnan, the Nobel winner in chemistry, former president of the Royal Society, and author of the incredible book why We Die. Venki, warm welcome.

[B]

Thank you.

[A]

You start your book with the pharaohs of Egypt who believed they could transcend death. Why did you begin there?

[B]

Well, the pharaohs are an interesting story because humans try to avoid death by a variety of strategies. Plan A is simply to try not to die. Plan B is to try to believe that even if you die, your whole body will be resurrected and you will go to some paradise. And plan C is that maybe your body will decay, but you will have an immortal soul that will outlast you and you can occupy other bodies and so on.

[A]

So now, many thousand years later, how close are we to living forever?

[B]

I think there's no physical or chemical law saying that our lifespan has to be what it is today. I mean, if you look at it today, we can expect at the most to live to be about 110 to maybe 120 years. Only one person has exceeded 120 years. But saying there's no physical law doesn't mean anything because there's no physical law that we can't eventually colonize other galaxies. But if you look at all of the difficulties involved, even in going to Mars, you realize that it's incredibly hard. And so I put this long life extension hundreds of years in that category, which is highly unrealistic today, despite what you may hear from various people promoting

[A]

hype, what's actually going on inside ourselves as we get older?

[B]

Well, many things happen. So one is that our molecules get damaged, and a primary source of damage is if you damage your DNA so that it is problematic, it results in two things. One is the cell can sense the damage, and it can send the cell into a program called senescence, where it doesn't function normally and in fact, secretes Inflammatory compounds. Now, early in life, this is a cancer prevention mechanism because if you have damaged DNA, you don't want that cell to hang around because it may mutate into a cancer cell. This is a mechanism to get rid of these cells where damage is sensed. But if the damage persists, it can also alter the genesis that are part of the genetic program and that can also cause dysfunction. There are ways that molecular damage can cause dysfunction. Now this damage then results in the cell itself not regulating itself properly. The organelles in our cell, called mitochondria, which have their own DNA, but also interact with the rest of the cell, they also can get damaged quite a lot. You can see these kinds of damages occur due to all kinds of things. Exposure to chemicals, even water alone can cause DNA damage. That was discovered by Thomas Lindahl, for which he won the Nobel Prize. Just the act of living causes damage, but we have sophisticated repair mechanisms that constantly repair the damage. But at some point the damage starts accumulating with age. Those mechanisms are never perfect.

[A]

Demi Sasabis, who won the Nobel Prize for everfold, he predicts that within 10 to 15 years there won't be any illnesses left. Any what potential that there won't be any illnesses left.

[B]

Yes, I know.

[A]

Potentially, potentially.

[B]

I actually know Demis quite well and in fact he asked me to be on the advisory board of one of his companies, Isomorphic Labs. And I think he's a brilliant guy. However, I would say in this case maybe he's being a bit over optimistic. And the reason I say that is not because AI won't give us clues about potential drugs or even causes, for example, of diseases. But I think going from there to having treatments is a complicated process. And it doesn't happen in the digital world. It happens in real people. You have to have real medicines, real, you know, which you make. So all of that stuff is in the analog world. And I think that is going to take longer than you do.

[A]

The tech people just think that life is a software that can be hacked.

[B]

Yes, I think they have that bias, whether it's conscious or not. They do have the bias of looking at the entire world as if it's a software problem. And the world is not digital. The world is analog. And I think they simply don't want to confront that.

[A]

Why is there suddenly so much money going into longevity research? Like tens and tens of billions?

[B]

I think there are two reasons. One is the one you pointed out, for example, about Japan, which is true of all societies, all societies are getting older and governments and health agencies are Extremely worried. How do we deal with societies where a huge fraction of the population is quite old and there's a smaller and smaller fraction of the population that's of working age that can support them? Okay, so the one solution is to try to put money into aging research. And this is the, the goal of this is not what you described earlier, of living for a very long time, but rather to make your life health as healthy as possible, but not necessarily extending life, but more increasing health span rather than lifespan. Okay. The fraction of life you're healthy, that's one reason, and that's a very widespread reason. Everybody will sign up to it. But the other reason is that there is a group of people who just have these grandiose visions and it's all based on the fact that they made billions of dollars in their 20s before they were mature. And they simply think that everything is just going to go their way. And these people don't want to die. Okay.

[A]

I mean, why, why don't they want to die?

[B]

Well, they love their lives. They like the feeling of control. They think, oh, we solved the problem of, of payment transactions so we should be able to solve debt.

[A]

Why are they all, why are they all men?

[B]

I, I do think, you know, they're all middle aged men, often married to younger women, by the way, which is a strong incentive to want to live longer. But, but I should say maybe it's some male thing, you know, of wanting control and so on. You're right. You know, and I do point out in the book that they're mostly middle aged men.

[A]

Now, in the meantime, we just want some more healthy years and so where do, where do we start?

[B]

Well, you know, caloric restriction pathways suggest an obvious answer.

[A]

One is, so this is basically just being hungry.

[B]

No, I don't think you need to be hungry. You're right that people on a truly caloric restricted diet, they're hungry all the time.

[A]

Which is why I don't do it.

[B]

No, and nor do I. Okay. But you can eat moderately and you can try to not be obese. You can control your weight. By the way, GLP1 drugs have now shown all kinds of effects, not just for preventing diabetes or for extreme obesity. And so they could be investigated further as well. And they also.

[A]

Do you think they'll extend, do you think they'll extend lifetime?

[B]

They might, I don't know about extending life, but they might make it old age healthier.

[A]

Do you think gratitude makes you live longer?

[B]

I don't know if, I don't know if any of these things particularly make you live longer I think you know some things you do because they're worth doing not just because everything is not about living longer it's about enjoying life while you have it right.

[A]

Are you afraid of dying?

[B]

I think we all are at some level but I think I mean my father and my brother in law both died in the last year and a half and my father was almost 99 and I would say he faced when he was told look now you only have a few days left you know he was a little bit sad that it was going to be over but I think he took it reasonably well and my brother in law you know he suffered from sudden diagnosis of pancreatic cancer but really you know was very measured and you know sort of rational about it so I hope if you know not if but when my time comes that I'll face it with the same kind of you know equanimity or rationality that that I saw in these.
