I don't like pictures like this, they always look like wallpapers and weirdly artificial

I love diving in aviation fuel. The fuel tank seats are genuimely the most relaxing. Like an isolation tank, except you get to slosh up against the other passergers every time the aircraft makes a maneuver. nice, cozy, intimate, communal and lubey experience.

Why do trees stems grow new "parts" inside and not outside i.e. why is the oldest part of the stem the innermost "ring" and not the outermost?

Wouldn’t grow something from the inside require a very strong force to “move” the already present one? Instead growing from the last “layer” towards the outside would require a lot less force, but perhaps a lot more matter....

Generally in trees you have the xylem in the middle which transports water and minerals from the roots to the rest of the plant. You have the phloem on the outside, it transports photosynthetic products and nutrients to all parts of the plant. The cambium where growth happens sits between them, because there they get easy access to water minerals and nutrients. The xylem is a mix of living and dead cells. The tracheids and vessel elements in the xylem, which are responsible for water transport, are dead at maturity. So it’s probably too hard to move them to grow from the inside out for trees. This whole process of growing thicker is called secondary growth as opposed to primary growth at the tips of stems and roots.

Also if were the other way around and trees would grow from the inside out, you’d have to have vessels going from the leaves to the center of the stems to deliver nutrients, which just complicates everything. And the tree wanted to grow from the inside by 1cm, every “ring” in the xylem would have to grow one centimeter longer in circumference or crack. It’s much easier to just add a layer on the outside. Also having living layer around the tree probably helps it defend itself from pathogens. If all the mostly dead woody stuff was on the outside fungi etc would have an easier time invading, I think.

Predestination (2014) would have been a fun one too

Lack of participation in the stock market is one of the biggest reasons why the bottom 80% have slowly lost their wealth in the last 50 years. In this inflationary scam system, you have to secure your wealth somehow. Stocks are a great way to do that. The government is pumping a large part of the money it stole through inflation into the stock market. That’s one of the biggest reasons why the rich are getting richer and the poor are getting poorer.

Ideally you would have a money system where the average person doesn’t have to worry about that stuff. But alas, here we are.

The price of Campbell’s Tomato Soup used to be steady at 0.1$ for 70 years, but its price increased by 10x in the last 52 years since we changed to this reverse Robinhood money system.
