2/ First, the stats that matter for context:

• Pre-1960: Singapore had <50 medical specialists for 2M residents
• 1964: GDP of $0.89B
• 1983: GDP grew to $18B

Ozempic isn't a miracle weight loss drug.

It’s medically induced anorexia.

Most doctors won't tell you this, but this weight loss comes with a terrible price.

As a new administration comes in, I expect to hear more about how banning seed oils or disincentivizing ultraprocessed foods is "unscientific".

Here's the story of how "scientific consensus" kept trans fats legal for 60 years: 2/ Modern medicine excels at acute care.

Car accident? You're in good hands.

There are 40,000+ chemicals in American products, food, and water that have never been safety tested.

And tens of thousands more toxic chemicals (like glyphosate) that are considered safe due to low exposure levels.

Ever wonder how these safe exposure levels are determined? Spoiler: It's not as scientific as you'd hope.

The process, roughly, goes like this:
-ChemCo invents a chemical that makes your eggs not stick
-ChemCo runs their own tests, tells FDA it's safe
-The novel chemical hits the market

1/ Some thoughts on the relationship between wealth and happiness:

(Inspired by the @naval and Joe Rogan podcast of a few days ago) 2/ The latin term “via negitiva” means “by subtraction”. Often used in context of bettering your life: instead of focusing on adding, try to subtract negative.

End a toxic relationship? Leave a bad job? That'll improve your happiness “via negitiva” - happiness by subtraction.
