**The Popeye Myth is that spinach contains lots of iron.**

**According to Brainpickings website**

**Back in 1870, Erich Von Wolf , a German chemist, examined the amount of iron within spinach, among many other green vegetables. In recording his findings, he accidentally misplaced a decimal point when transcribing data from his notebook, changing the iron content in spinach from 3.5 milligrams of iron in a 100-gram serving of spinach, to 35 milligrams. It was corrected in 1937, but too late the myth was well established.**

**This study inspired the Popeye Cartoon character who gets colossal strength eating cans of spinach.**

**Unfortunately, it was just a maths blooper. The good news is that:**

**Popeye Myth Busted.**

**Spinach does not have that much more iron than other vegetables.**

**Can’t those scientists count?**

…….……..………

**According to Shamini Bundell on Null Hypothesis**

.....

….**Various experts have tried counting the muscles involved. Mainly they argue over how to define a smile and a frown and come up with different answers.**

**Either way most of the numbers quoted at you by irritatingly cheerful people are entirely made up.**

**As Shamini noted “It takes 37 muscles to frown and 22 to smile, but it only takes 4 to reach out and punch someone in the face.”**

**One hiccup cure involves counting backwards from 100. **

**That’s maths folks! And maths seems a less painful cure than poking yourself in the eyes, drinking water with your nose blocked, drinking water through your nose or putting your fingers in your ears.**

**An extensive post on Wiki How notes:**

** ‘Interestingly, some of these folk remedies are on the correct path by having at least some basis in the science of the hiccup and singultus. With home remedies, the methods that attempt to relax or stimulate the diaphragm tend to be the most effective.’**

**This is obviously ridiculous from your own experience. If you stand in the middle of a road or in the middle of a basketball or tennis court or football field and you don’t see a rat as in a rodent then you disprove the myth.**

**
According to Animal Planet:**

**Cool rat, man!**

**Many rodent-related myths focus on how many rats exist per capita in any given metropolis — often on par with the human population — but that’s pure farce.**

**It stems in large part from a coincidental study conducted in the early 1900s, which vaguely pegged England’s rat population at about 40 million — or 1 acre of cultivated land per rat. Since at the time approximately 40 million people lived in England, people have long equated these two unrelated statistics to infer that modern cities contain equal numbers of rats and people.**

**In other words, this myth has hung around for over 100 years! **

**Rat Myth Busted**

**Could this be 6 fleas of separation?**
