It was a widely held assumption up until about three decades ago, in the 1980s, that stress increased the development of acidic liquids in the stomach and led to ulcers. While arguing that stress can contribute to and exacerbate gastric ulcer symptoms, recent research contradicts this theory and shows that the Helicobacter pylori, or H. pylori, bacterium is present in over 90% of cases. Its presence can be detected using a stool, blood, or breath test, and antibiotics work well to treat it.

We've all been caught jaywalking. You will NOT see jaywalking during your vacation here, even though it is rather widespread in other world areas. This is one of the fascinating facts about South Korea that may take some getting accustomed to. South Koreans are extremely conscientious about traffic and pedestrian restrictions, therefore they will always wait for visual confirmation that they are permitted to cross the street, even if the crossing is clear! Fortunately, in a densely populated city such as Seoul, this results in safer streets and fewer traffic accidents.

Have you ever thought about why you get hiccups? The spasms in your diaphragm compel you to suck in a breath, producing a gulping sound in your voicebox. Hiccups aren't beneficial in today's society, yet they were 370 million years ago. Scientists think that our ancestors had both gills and lungs and that when they pulled water in via their gills, it might aspirate into their lungs. A well-timed hiccup would clear the airway and prevent choking. Even though we no longer have gills, we still love the occasional hiccup!

According to the report, Madagascar is the 14th unhappiest country in the world.

A fog bow, as the name implies, is a rainbow that appears in fog rather than during rainfall. They are slightly fainter and more difficult to see than rainbows, but you are more likely to see the entire circle of the optical effect. Because fog is made up of smaller water droplets than raindrops, the full spectrum of colours in a fog bow is difficult to distinguish and appears as a bow of faint red and blue.

Roses also produce a berry-shaped fruit known as 'rose hips.' The fruit may be orange, red, dark purple, or even black in color. Rose hips are high in vitamin C and can be dried to make a tasty tea.
