[For Seniors] Trivia Quiz & Fun Facts for June

0 days

Actually, there are no public holidays in June. After the Golden Week holidays in May, June doesn’t have a single public holiday, so I think many students and working adults feel disappointed. By the way, the only months with no public holidays are June and December, but since there are year-end breaks in December, June is truly the only month without any days off.

rheumatism

June brings a lot of rain and higher humidity, doesn’t it? In fact, some people with rheumatoid conditions are more likely to experience symptoms due to humidity and low atmospheric pressure. Especially during the rainy season and before typhoons, it’s a good idea to check the weather forecast carefully and take early measures such as taking pain relievers or dehumidifying your room.

pearl

Pearl, also well known as the birthstone for those born in June, is called “shinju” in Japanese. Pearls are gemstones obtained from shellfish and are characterized by their refined luster. Because they are minerals produced by living organisms, they are also called biominerals, and they are known as gemstones of very high rarity and value.

shrink

The answer is “shrink.” Like slugs, snails have a thin membrane covering their body surface. This membrane allows water to pass through but is relatively impermeable to salt. When salt is applied, the salt concentration outside the membrane rises rapidly, causing osmosis—a phenomenon where water inside the body moves toward the area of higher concentration. As the body loses water, the cells shrink and their functions are impaired, which is why snails shrivel up when salt is sprinkled on them.

Concrete

Snails mainly prefer to eat plant leaves. The nutrients they obtain from leaves are very important for their growth. On the other hand, it is also said that they eat concrete itself or lick the calcium that seeps out of wet concrete.

Germany

The birthplace of the folding umbrella is Germany. It was invented by Hans Haupt in 1928 and patented in 1932. The first folding umbrella made at that time was produced under the brand name Knirps, and in Europe, Knirps is fondly used as a synonym for folding umbrellas.

Hokkaido

Most regions of Japan have a rainy season, but Hokkaido does not. This is because the seasonal rain front that brings the rainy season has little effect on Hokkaido.
