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

The average 22-year-old male has the same testosterone as a 67-year-old male...

In the year 2000.

Just 23 years ago.

Why is this happening, and what can be done about it? It's impossible to overstate the importance of testosterone.

It is crucial to your:

• Energy
• Mood
• Muscle growth
• Libido
• Cognitive function

Basically, name a bodily function, and there's a good chance testosterone affects it.

Where they’re less incredible?

Innovation.

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.

1/ In my last thread (below), I talked about the health drawbacks of Beyond Meat ($BYND) and Impossible foods.

Now let’s talk about the health of their businesses. 2/ Spoiler alert - I am incredibly skeptical, and am short $BYND (as 44% of $BYND shareholders appear to also be).

1/n A quick tweetstorm about why I think Beyond Meat ($BYND) and Impossible Foods are the trans fat purveyors of our generation. 2/ Let’s start with Beyond Meat. For those that don’t know, $BYND’s flagship product is their Beyond Burger - a pea-protein product that’s supposed to replace the standard ground beef patty.
