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.

Inversion: Avoiding stupidity is easier than trying to be brilliant. Instead of asking, “How can I help my company?” you should ask, “What’s hurting my company the most and how can I avoid it?” Identify obvious failure points, and steer clear of them.

Perverse Incentives Select for People Who Are the Best at Exploiting a Given System
Summary:
The original deans and administrators burn out due to their dislike of the US News and World Report rankings and are replaced by individuals driven by ranking success.
This shift reflects a difference in mentality between valuing money as a means of support versus valuing money as the sole purpose of life. Similarly, pursuing publications and citations for a job versus making them the ultimate goal shows a significant distinction.
However, these differences are connected through a temporal dynamic where initially people adapt their behavior to succeed in a flawed system.
The system then filters out those who can best exploit it, resulting in the selection of individuals with specific values.

What happens later on, the original deans and administrators burn out because of how much they hate the US news and rule report rankings, and they get replaced by people who are all it. They think the only point is to rise in the rankings. And those people don't hold back. They only have one target. I think something similar is the difference between so realizing I need a lot of money in order to a decent amount of money to support my family, but not thinking money is the point of life. And similarly, realizing that getting a decent number of publications and citations is necessary for a job versus thinking the goal of my life is to max out citations. And for me, there's a huge gulf between those things.
Speaker 1
Well, here's where I think they're connected because I see the difference and I understand the difference you're talking about. But I think the difference is that is this temporal dynamic, right, where you start out with, let's say, perverse incentives and people saying, well, I don't necessarily value these Things, but I have to shape my behavior in order to succeed in this system. But the thing is, the system being the way it is creates a filter. And the people who are the best at figuring out how to operate in that are the ones that then end up being successful. And they're the ones that teach the next generation or emulated by the next generation. And over time, the people for whatever reasons, psychologically or behaviorally or ever their path is, are best able to exploit the system are going to be able to thrive in it. And I think that because of that, you end up selecting for people with certain kinds of values, because they're going to be the people who there's always exceptions, but are going to Be best able to thrive in this kind of thing.
