During a health symposium @StanfordMed I learned from a cardiologist colleague that even if we get our 180min of zone 2 cardio per week, the benefits are largely (or entirely) erased by sitting >5 hours per day. Solution: standing (1:1 ratio w/sitting) & 3-4, 10min walks per day.

World is a highly efficient place.
Efficient market hypothesis
"If it were so easy, why wouldn't everyone else have done it already?" Thus if something seems easy and obvious to do, you must be missing something in it's difficulty However if an idea seem ridiculous on the surface, you can rest assure that less people have thought about it deeply.
Specifically for economic markets this is the idea that any predictable nature in the market will be exploited to maximum potential by everyone who knows about them. If you know a stock is underpriced, it makes sense to buy it until it is priced to equilibrium. This is how markets work.
- Naval claims this. And a followup conclusion is that there are rarely openings, opportunities. e.g. biology the way your hand skeleton, tendons work is highly efficient and it would be hard to design it from scratch to improve it
- I think this comes from the lack of imagination. There are wells of efficiency. Biology really optimize hand for the purpose of having four finger one direction and one in another. If we would want artificially build hand with that constraints using "human parts" and adding all functions this hand does currently it would be hard to come up with better design. But this view lacks imagination. How about adding 3rd hand or more fingers? I believe there are wells of efficiency – a limited areas that nature or culture excel in innovation and efficiency. But there are huge hole in between these silos there are huge breaks.
- There is that is highly inefficient and constraining (see example QWERTY vs. DVORAK)Foundation-Paralysis Effect 🎨
- Peter Thiel in his book "From Zero to One" sees the same thing in a technology. e.g. in a startup world if there is a possibility for a business its probably already existing. It's really hard to do a new big startup because as soon as the technological opportuinty opens up somebody will figure out and go into it.
- I believe there are hundreds of new social media startups possible right now with a technology we have currently but it's really hard to pull them off (idea, design, marketing). to explain why startups are possible in the world of large companies uses the following metaphor. When small planes are flying into big cloud it's not that they have radars. They cannot see where they are flying into. The reason it's safe to do is that this is humongous space and it's highly unlikely to crash with another plane.Paul Grahamsays that it's important and difficult excercise to distinguish weather some startup idea is impossible (yes, as soon as new technology opens new possibilities it is filled with new applications) or nobody thought about it or was able to bring a successful product. Patrick Collison asked why is this so hard to make a good app. There are so many bad apps. And I think that's the core of it. Why good apps are good is not obvious. There are many things synced, working that look minimalistic and obvious but took a lot of effort to arrive at.Paul Graham
In technology winner takes it all
Not sure if following is true. There are a lot of technologies that are existing in parallel. Maybe this applies more to technologies such as electrical circuits, algorithms.
If there are two competitors in the technology (does it more apply to technologies such as algorithms usually the one that is a little bit more effective tend to slowly snowball into a bit larger, a bit larger and eventually only
Nature or nurture
"Since the 1950s, the nonprofit Holt International has helped American families adopt tens of thousands of children from Korea and other countries. Parents would sign up, get approved, and get the next available child who fit their general criteria. The process was essentially random, which gave scientists an opportunity. They could compare genetically unrelated children who were assigned to the same parents: The more the parents influenced the children, the more these adopted brothers and sisters would end up alike.What the scientists found was that the family a kid was raised in had surprisingly little impact on how that kid ended up. Unrelated children adopted into the same home ended up only a little more similar than unrelated children who were raised separately. The effects of nature on a child’s future income were some 2.5 times larger than the effects of nurture.”
"Other researchers have done further studies of adoptees and twins, with similar results. As Bryan Caplan notes in his 2011 book, Selfish Reasons to Have More Kids, parents have only small effects on their children’s health, life expectancy, education, and religiosity (though studies have found that they have moderate effects on drug and alcohol use and sexual behavior, particularly during the teenage years, as well as how kids feel about their parents).”
This is beautiful moment.
I want to share how high am I on the hierarchy ladder.
Is taking notes on net positive?
It may be pretty effective strategy for for things you naturally tend to agree, things that expand your knowledge in an predictable manner.
That said these area of knowledge, perhaps in a smaller extend, is gonna be subjected to constant forgetting process as well.
But won’t work with thing you don’t understand, didn’t click, didn’t connect as an epiphany with different areas of knowledge, are on the verge of grasping. These ones will be discarded even though they have a high potential of being an important building blocks for knowledge.
Is this area actually expanding your understanding more effectively than the things you more naturally agree with?
