The Hedonic Treadmill

Knowing when to step off the treadmill and be happy

Hedonism is about finding pleasure and avoiding suffering. It ranges from the wild to the mild, but essentially it is a way of thinking where we want to be happy and should seek out ways of making ourselves happy.

The hedonic treadmill (also called hedonic adaptation) is an idea where each of us has a default level of happiness, and that our happiness will return to this default level despite life changes. If we make more money and start living a fancier lifestyle, what might make us a bit happier at first, soon becomes the new normal and we return to our default happiness level. We get more, we get used to it, and then it takes even more to make us (temporarily) happier again. It’s an arms race where it can constantly take more to feel happier and it can go on forever. Whatever the change, we tend to get used to the new speed of the treadmill.

The good news is that it also works the other way around. If we lose a job or some catastrophic accident befalls us, we can adapt to that as well and (over time) return to our default happiness level. In his TED talk on the science of happiness, Dan Gilbert discusses a study of lottery winners and people recently paralyzed, and that after a year both groups had returned to their pre-incident level of happiness. The treadmill can speed up or slow down but your happiness level will adapt.

Epicurus

Epicurus was a 4th century BCE Greek philosopher who created a school of philosophical thought, known today as Epicureanism. While the word “epicure” means someone with fine taste in food & alcohol, Epicureanism is a much deeper collection of teachings that have little to do with food. Epicurus was a hedonist, in that he felt happiness was good and pain was evil, however he taught that we should enjoy the simple pleasures of life. Happiness can be achieved through friendship and living a simple life. Perhaps it’s best to know when to step off the hedonic treadmill and appreciate what you have rather than running faster for more.

Carats, Karats, Carets, & Carrots

A crash-course on Carats (measures gems & pearls), Karats (measures gold purity), Carets (a symbol), and Carrots (popular with humans & rabbits)

Carat

The carat is a unit of measurement for the mass of gemstones and pearls. Each carat is equal to 200mg of mass. So the more carats, the larger the stone / pearl (basically the more it weighs). The word carat comes from the Italian “carato”, which comes from the Arabic “qirat” which means “fruit of the carob tree” and also “weight of 4 grains”, which also comes from the Greek “keration” for both the carob bean and a small weight.

Karat

Karat with a “k” is a measurement of gold purity. It comes from the same root word as Carat with a “c”, from the Greek “keration”. Gold products are frequently alloys, different blends of gold and one or more other metals. The karat measuring system is a 24 part system and tells you what the ratio is of gold to other metals. So 1 karat gold is 1 part gold mixed with 23 parts other metal(s). Pure gold is 24 karat and contains no other metals.

Interestingly, pure 24 karat gold is fairly soft and not very resilient for jewelry or coins. Silver, copper, and zinc have been popular metals to pair with gold. These other metals strengthen the gold to make it harder. This is not true of lead, which was sometimes used to make fake gold coins. This is where the idea of biting a gold coin comes from. Most real gold coins were hardened alloys and would not leave a tooth mark when bit, but fake gold coins used lead which would be soft and leave a mark.

Caret

A caret is this ^ , which is a typographical mark used by proofreaders to show where something needs to be inserted into an area of text. Caret comes from Latin for “there is lacking” or “it lacks.”

Carrot

Finally, the carrot we are most familiar with is the vegetable, which originated in Persia. Its name also comes from Greek but from “karōtón” meaning horn, since the vegetable has a slightly horn-like shape. Carrots are a healthy vegetable full of beta-Carotene which is a red-orange colored organic pigment. When we eat beta-Carotene it synthesizes into Vitamin A which is good for you (… in moderation). Due to its color, storing extremely excessive amounts of beta-Carotene (eating way too many carrots) has the side-effect of turning a person’s skin orange through stored deposits in the skin cells.

Under normal circumstances however, beta-Carotene is converted into Vitamin A and can give us healthy skin, a better immune system, and good vision. This last part about better vision is the foundation of the myth that British WWII pilots were such good shots because they ate their carrots. In reality, they secretly had on-board radar and didn’t want the Germans to know about it, so they started a propaganda campaign saying their ace shooing was all due to carrots (which the British had an abundance of).

Oil’s Origins

Oil doesn’t come from dinosaurs, it comes from plankton.

When people hear “fossil fuels” they sometimes think that oil (petroleum) came from dinosaur fossils. This isn’t out of left field. At the Chicago World’s Fair of 1933-34 Sinclair Oil sponsored an exhibit that taught people that oil was formed during the time of the dinosaurs. Reinforcing this idea there’s also the logo & mascot for Sinclair Oil, Dino the dinosaur. Sinclair again pushed this connection of dinosaurs & oil at the New York World’s Fair in 1964 even though the science had become pretty clear that oil wasn’t made from dinosaurs. So what makes oil? Plankton.

What are plankton?

Plankton are water dwelling life forms that (more or less) drift with the current. The name “plankton” actually comes from the Greek for “wanderer” or “drifter” which makes them sound like edgy antiheroes in a pulp novel. There are lots of different kinds and sizes of plankton, and they fill all sorts of ecological roles ranging from being food for larger organisms to producing 50% of the Earth’s oxygen. Bacterial plankton formed in the oceans 3 billion years ago and were basically the only form of life until 600 million years ago. That’s an enormous amount of time. So as plankton over that time died, most fell to the bottom of the sea floor and began the process of becoming oil.

Let’s make oil

Lots can happen during hundreds of millions of years. The plankton that fell to the bottom of the oceans continued to accumulate as well as other sediment. The plankton would decompose releasing most of their chemicals but the hydrogen & carbon would remain. This continuous process of plankton and other sediment falling to the ocean floor meant that the former material would be pushed further down and compacted under intense pressure over millions of years, generating heat. It was this pressure and heat that “cooked” all of those plankton into oil.

While it is certainly possible that some dinosaurs may have found themselves a part of this oil making process, it’s just very unlikely they made up much oil – they usually weren’t in the right places and there weren’t enough dinosaurs (not enough raw material to cook with). Instead of being made from some of the Earth’s largest creatures, oil was made from massive amounts of some of the smallest.

Bond … James Bond, ornithologist

James Bond’s name was taken from a Philadelphia ornithologist

Ian Fleming was living in Jamaica while writing what would become his first James Bond novel, 1953’s Casino Royal. What he needed was a good solid name for his protagonist, a name that very “flat and quiet”. Fleming was an avid bird watcher and had a copy of Birds of the West Indies by Philadelphia ornithologist James Bond, which he felt would be the perfect name. Fleming later said that:

“I wanted the simplest, dullest, plainest-sounding name I could find, and ‘James Bond’ was much better than something more interesting, like ‘Peregrine Carruthers.’ Exotic things would happen to and around him, but he would be a neutral figure — an anonymous, blunt instrument wielded by a government department.”

The real life James Bond was a celebrated expert in birds of the Caribbean and worked for decades at the Academy of Natural Sciences in Philadelphia. He was unaware of his name’s new found fame until the 007 books became popular in the United States. Bond and his wife paid Fleming an unannounced visit in 1964 while in Jamaica, and presumably things went well because Fleming gave a first edition of You Only Live Twice dedicated to Bond, “To the real James Bond, from the thief of his identity”. In 2008 this dedicated copy sold at auction for $84,000.

Added info: in 2002’s Die Another Day, Bond’s Birds of the West Indies appears in the film being held by, well, Bond, but with the real life author’s name obscured. Pierce Brosnan’s Bond later identifies himself as an ornithologist.
