This doesn't mean you should increase your cholesterol.

Low cholesterol (hypocholesterolemia) is commonly observed in critically ill patients. This could be driving the correlation and doesn't mean that if you lower your cholesterol you will increase your risk of dying.

Actually Apo B is a better predictor for cardiovascular risk (and, AFAIK, the actual thing that injuries your arterial wall): "Based on current research, Apolipoprotein B has emerged as the superior marker for assessing cardiovascular disease risk. LDL particle size also has quality evidence behind it, but as it’s a metric that’s not yet as standardized nor as strongly predictive as ApoB, ApoB remains a better assessment of heart health than LDL particle size alone." https://blog.insidetracker.com/impact-ldl-particle-size-apob...

cuchoi··on Analysis finds Australia’s inflation being driven by company profits, not wages
It is a pretty common concept among economists. IIRC it is even covered in Mankiw's Introduction to Economics textbook.
cuchoi··on The Absurdity of Income Tax
What is fair? For people that can save most of their money, VAT is a neglible proportion of their income. Poor people which spend all of their money (and more!) will pay a lot of VAT proportional to their income.

The first person might pay more in absolute terms, but that doesn't sound fair to me.

cuchoi··on 1min high-intensity exercise 3x a week improves fitness as much as 3x aerobics (2016)
Under-powered also means that the minimum detectable effect is high (that's why it is harder to get a "significant" result).

Which means that it is more likely that if you will find an effect only if you are overestimating the real effect. The real effect might not even be detectable!

cuchoi··on Tell HN: Airbnb has no system in place when a host cancels on a renter
Once our host gave us the wrong key, had no way of getting us the correct one, and they just wanted to cancel the reservation. This was 9pm and there was curfew due to COVID restrictions, so we were not allowed to go outside the building. I had to beg for about 4 hours to the rude host so they do not cancel the reservation and to call a locksmith. Airbnb's answer was that it was all good because we were able to get in.

cuchoi··on How international money transfers work (2016) [video]
Love monito.com! Congratulations on your product. Do you know why so many money transfer system have restrictions on the directions to send money? For example, Wise only allows sending in the USA (USD) -> Chile (CLP) direction but not the other way around. Also Moneygram only allows USA -> Chile and it is blocked from non-US IP adresses.
cuchoi··on Ask HN: Why is cryptocurrency so hated here?
My grandparents and parents love WhatsApp, Uber, Instacart, 4G, Smartphones, Ipads, and Netflix (to give a few examples). All things that were invented long after they were 35. I am between 15 and 35 and I have yet to see the problems Bitcoin solve for me (TBF, I don't live in Venezuela or Argentina, and I don't do any illegal activities). I am bit more bullish on Ethereum.

cuchoi··on Evaluating necessity of Covid-19 vaccination in previously infected individuals
Had the same symptoms both times (dry cough for 5 weeks, using inhalator, loss of smell, etc.). It could have been a very a flu very similar to COVID at the exact time NYC was locking down due to COVID?
