All my life I have heard the phrase, “correlation is not causation.”
And like many, I had no clue what it meant.
But today, I use this phrase all the time. And boiled down, “correlation is not causation” means that just because two things correlate does not necessarily mean that one causes the other.
I find it is best to use examples to better explain this:
Every time my face breaks out with acne, the sun rises in the east. This scenario is 100% correlation. But we all know the sun rising does not cause my face breaking out.
Thus, correlation is not causation.
Here is another interesting example…
When Crisco was invented in 1911, scientists discovered atherosclerosis developed about a decade later. This is why we have this war on transfats today.
Statisticians have claimed that Crisco both correlated and caused heart disease. But there has never been a proper scientific study showing a causal link between trans fats and atherosclerosis. I have not seen a single study proving this causation (and I have been hunting one down for most of my adult life). Thus, correlation is not causation…
By the way, there is WAY more potential causal evidence that the introduction of chlorinated water into our water supply is more likely to have a direct link to heart disease.
It is true: Steve Jobs and Steve Wozniak were the founders of Apple Computer.
But there was a secret 3rd founder, too. And his name is Ronald Wayne. He was a 10% owner of Apple.
He even designed Apple Computer’s first logo – check it out:
Just 2 weeks after founding Apple Computer, Ronald Wayne was forced to sell all his Apple stock holdings.
At the time of Apple’s founding, the 3 founders formed a partnership, not a corporation.
This became an immediate issue. Because Ronald Wayne’s failing business (a slot machine company) presented a legal problem. Legally, all members of a partnership are personally responsible for any debts incurred by any partner.
In order to protect Apple from Wayne’s failing business debts, he was forced to sell his holdings. He relinquished his equity for just $800. And he never reinvested back into Apple Computer.
Here is the fascinating part. If Ronald Wayne would have remained a 10% stockholder, he would be worth tens of billions of dollars today.
Instead, Wayne retired to a mobile home park in Pahrump, Nevada. Ironically, he never purchased an Apple product. (Allegedly, he was given an iPad 2 at the Update Conference in Brighton, England in 2011.)
This terrific documentary about the Macintosh Computer features a seldom seen video of Ronald Wayne – about 2 minutes in:
Now the robots are taking over our farms:
Sweeper is an autonomous bot that detects and harvests mature sweet peppers. Developed to give Europe a leading edge in agricultural robotics, the bot is considered a first-gen “greenhouse harvesting robot.” Sweeper is built on an autonomous moving platform and uses a robotic arm with plenty of sensors to manipulate crops. The bot can maneuver its way autonomously through the crop until it detects a mature pepper. It can scan the bottoms of the veggies to determine the maturity of the peppers. Once it selects a mature pepper, sweeper approaches it and a cutting tool is deployed to harvest it.
A lot of people complain that robots are killing jobs. But does someone REALLY enjoy picking peppers all day long?
Wanna see how travel vloggers are wined and dined to pimp the latest and greatest airplane seat?
Warning: it gets cheesy at times. Check out this behind-the-scenes video:
Here is the same flight from travel vlogger Sam Chui’s point of view:
Fun fact: Singapore Airlines now travel the longest flight in the world – from Newark, New Jersey to Singapore in 17 hours and 20 minutes.
In this book, Tim Ferris is a big believer of the minimum effective dose. It is simply the smallest dose that will produce the desired outcome. He finds anything BEYOND the M.E.D. is wasteful.
Take working out. Ferriss claims instead of working out 1 hour a day for 5 days a week, we can swing a Kettlebell just 2 to 3 sets per week and get similar results.
This is the best training video I could found on Kettlebell swings:
Here are a few tips I find while researching Kettlebell swings:
About Kettlebell weight: Men typically start off too heavy (ego kickin’ in). For ballistic movements like Kettlebell swings, an active man should start out with either a 16 kg- 35 lb or a 20 kg – 44 lb Kettlebell. Athletic men should start with a Kettlebell between 16 kg – 35 lb and 24 kg – 53 lb…
Unlike men, women tend to start out with a Kettlebell that is too light for them. For ballistic movements like Kettlebell swings, active women should start with a Kettlebell between 8 kg – 18 lb and 12 kg – 26 lb. An athletic woman should start with a Kettlebell between 12 kg – 26 lb and 16 kg – 35 lb. Out of shape, inactive women should try a bell between 6 kg – 13 lb and 8 kg – 18 lb.
Make sure our stance is not wider than shoulder-width. Too wide, and it becomes more difficult for our knees to track our toes. (Our knees must always track our toes).
Also, make sure we are not hyperextending our knees at the top. So instead of throwing our knees “back” at the top, think instead of pulling our kneecaps “up”.
To avoid problems with hip-flexor tendonitis, do a static stretch for our hip flexors before exercising. Lay on our stomach and pull our lower leg to the glutes. Hold for 60 seconds on each side.
