Today I learned that cleaning a white hat can be done with bleach cleaner, but it’s important to rinse it before wearing it again. I also discovered that "oyster veneering," a woodworking technique from the late 1600s, is experiencing a minor revival despite its labor-intensive nature. Additionally, I learned that the factorial of 23 (23!) equals 25,852,016,738,884,976,640,000, which interestingly has 23 digits, a unique coincidence among factorials. I found out that medical specialists often spend less than 10 minutes with patients, and that watching TV can contribute to weight gain. Other insights included the fact that a kiss can transfer around 80 million microbes, and that bureaucracy can sometimes hinder employment opportunities. The discussion also touched on various trivia, such as the emotional sensitivity of barn owls and the complexities of gravitational lensing around black holes.

Tanigawa-dake is sometimes called "mountain of death". As of December 2014, since its initial exploration and route-finding in the early 1930s, a total of 805 people have died on Tanigawa-dake.[1][2][3] (Compare with the approximately 200 people who have died on Mt. Everest over a comparable period.) In 1943, a climbing party disappeared on the mountain. They were not found until another climbing party stumbled upon their remains in 1973. In the 1960s, there was a famous rescue attempt of Japanese climbers on the main face who had died of exposure. Their bodies were eventually brought down when the Japanese Self-Defense Forces cut the rope with gunfire in order to retrieve the bodies.[4]

Learned about this alleged airburst that destroyed an ancient Mesopotamian city in the otherwise good The Earth Transformed by Frank Pankopan. The story came out in Nature and the Smithsonian Article referenced below, the wiki article indicates considerable skepticism has arisen over the last few years though



The destruction of Tall el-Hammam, a Bronze Age city in the Jordan Valley, by an exploding comet or meteor may have inspired the biblical story of Sodom and Gomorrah, a new study suggests. (“[N]otoriously sinful cities,” Sodom and Gomorrah’s devastation by sulfur and fire is recorded in the Book of Genesis, according to Encyclopedia Britannica.)

TIL that Florida's state bird is not the flamingo. It’s the mockingbird. This year will see the eighth attempt to fix that, in the state legislature.

I assume all "Bill to kill the Mockingbird" jokes have already been done?

For almost 29 years after the end of World War Two, Hiroo Onoda carried out guerrilla warfare on Lubang Island in the Philippines, on several occasions engaging in shootouts with locals and the police. Onoda initially held out with three other soldiers: one surrendered in 1950, and two who were killed, one in 1954 and one in 1972. They did not believe flyers saying that the war was over. Onoda was contacted in 1974 by a Japanese explorer, but still refused to surrender until he was relieved of duty by his former commanding officer, Major Yoshimi Taniguchi, who flew from Japan to Lubang to issue the order.

Onoda surrendered on 10 March 1974 and received a hero's welcome when he returned to Japan. That year he wrote and published his autobiography. He later followed his brother to Brazil, where he joined an established Japanese immigrant community in Mato Grosso do Sul. He set up a cattle ranch. After 1984, he spent three months of the year in Brazil and the rest of his time in Japan

Pacific bluefin tuna are large, migratory fish found throughout the biggest ocean on Earth. A typical Pacific bluefin weighs about 130 pounds, but occasionally, these iridescent swimmers can balloon in size, topping the scales at nearly 1,000 pounds. They feast on squid and various types of fish, including herring, anchovies, saury, sardines and mackerel.

Unlike most other fish, bluefin tuna are warm-blooded. They have a unique blood vessel structure, known as a countercurrent exchanger, that allows them to retain body heat, even when they’re submerged in frigid waters. This adaptation allows them to inhabit cold areas and dive up to 1,800 feet deep. It also makes them fast and powerful swimmers: The fish are known to cross the Pacific Ocean in just 55 days.

Are you some kind of terrorist? Jeez!

Actually, it is a gesture that can mean, I'm going to kill you. So it is understandable.

In some areas of Japan the finger gun is such a tradition that victims will pretend to have been hit. Even strangers will do this.

My uncle played semi professional football in the 1950s-70s. I know he played for Hyde United and was a Manchester "boys" player as a kid. I am researching his other clubs, he died 2017. His hero Denis Law died yesterday, the last of the famous United Trinity. Worth a mention at least RIP.

True. But fun game.

Clearly Detroit was impacted by all their injuries.
Detroit should have kept going to Gibbs. That guy is awesome!
