Why Bigger Animals Live Longer: The Relationship between Size, Energy, and Longevity
Summary:
The larger an animal is, the more efficient it becomes in terms of energy consumption.
This is because the self-similar fractal structure of larger animals allows them to save energy. Bigger animals require less energy proportionally to run their bodies due to the massive amount of tissue per gram or per cell.
As a result, bigger animals experience less wear and tear and live longer than smaller animals.
The reason for less wear and tear is that bigger animals use less energy and create less damage, reducing entropy.
This principle can also be observed in machines, where those subjected to less stress and driven at lower revs per minute tend to last longer.

So that's why we don't need to double our metabolism when we double our weight. It's that fractal like self similarity that allows us to get these essentially efficient savings in the amount of energy we need. So it's better to be bigger, isn't it? Because you don't need as much energy proportionally to run yourself. Correct.
Speaker 1
So you need massive tissue per gram of tissue or per cell. You need less energy, the bigger you are. And by the way, this has huge consequences throughout all aspects of biology and life. And maybe one just to tie it back to the beginning of this discussion where we started out by talking about aging and mortality. This means that the bigger you are, the less hard your cell is working. The bigger you are, there's less wear and tear the longer you live systematically. So this is the origin of why bigger things live longer than smaller things.
Speaker 2
And why is there less wear and tear if you're bigger?
Speaker 1
You're using less energy and creating less entropy. That is you're creating less damage the bigger you are because simply you're using much less energy if you have an engine, an automobile and you insist on racing it at 10,000 revs per Minute every time you drive it, I can assure you that car will not live as long as a car that's driven by a little old lady or a little old man like me who keeps the revs at about two or three Thousand revs per minute. So you know, cars and machines last much longer, the less stress you put on them.

Source of the Meaning Crisis: Contradictions Between Societal Progress and Global Crises
Summary:
The current societal malaise and victimhood culture are attributed to a complex interplay of factors, including a disconnection from the positives of societal progress and the simultaneous awareness of global crises like climate change.
The author explains that while the world is objectively getting better, the incessant exposure to negative news triggers hyper-vigilance and threat response, leading to a cognitive dissonance between feeling alive and needing to practice triage. This contradictory experience fosters a sense of confusion and psychological distress in individuals, creating a state of being 'crazy making.'

Speaker 2
You because you wrote a book recently called recapture the Rapture, which is trying to address the seeming sort of psychological ills of our society. Can you try and sort of summarize what your thesis is on why it seems like victimhood culture has become so dominant? Disconnection, general malaise people are having, is it, is it a function of, you know, fear of the future? We've been hearing, you know, doom and gloom from climate change and all these other growing risks? Or is it something more fundamental going on inside a psychologically that is giving rise to this? I mean, I think without a doubt, like, what on earth is going wrong these days? And why are so many people sad, suffering, disconnected?
Speaker 1
I think that's just a massive, multi-variable situation. But one of the things that I mentioned in that book was just things are getting exponentially better, and things are getting exponentially worse at the very same time. And trying to map to intersecting, contradicting, overlapping, exponential curves. Confusing. Back as the imagination. I mean, with the whole three-body problem in physics, which I know you must be deeply aware of, everybody, it's very hard to be like sun and moon and stars, you know, like you get you. Panotales, ah! Yeah, and we are eight billion bodies, all with volition, you know, and pesky human nature. So trying to map what is going on as things are simultaneously Stephen Pinker and Hans Rosling, and all the lot of like, if it bleeds, it leads, you've been massively misled. The world is safer, better, cheaper, more prosperous than it's ever been. Ta-da. And you're like, oh, thank God. And then you click over to polar bears and, you know, throw it to Glacier and all of these things, you're like, oh, no, which is it? Right. So as we have that initial experience, which naturally triggers hyper-vigilance and threat response, oh, shit. Right? Are we coming alive? All this wonderful stuff. My own personal life, my personal growth, my relationships, my career, where am I coming alive? That's the inquiry I'm in. Or are we staying alive? And I need to be practicing triage, right? And in a threat response and toggling back and forth between those two is crazy making.

People's Understanding of Others' Lives Is Biased Based on the Structure of Their Social Network
Transcript:
Speaker 1
So there's something in that that I found really interesting about this social sampling, which is that as you mentioned, like if you happen to be worse off and everyone else is worse Off, as is the case with like income, for example, then being worse off, you're going to project your bias into that general population more accurately than if you're better off in some Situation for which the most of the population is worse off. And that these biases are not all created equal. Yes. It has to do with how they stand relative to the broader population. So what we show is that this kind of biases of judgments of the broader population can be explained by the structure of social network and not by some cognitive deficit or motivational, Motivational bias, some desire to be better than others or that or some idea that everybody's like me or some cognitive deficit that people cannot, that people are too stupid to understand How other people live. It's really determined by the context of memory, that by the content of one's memory, which comes from one social circle.
