The CDC Makes It Official: Public Pools Are Disgusting

Every summer, warm weather sends people across the country looking for a cool refuge in public pools, hotel pools, spas, and other water-based destinations. Before you take the plunge, you may want to heed the advice of the Centers for Disease Control and Prevention (CDC). Jumping into a publicly-populated pool could be like bathing in someone else’s diarrhea, as Men’s Health reports.

The health agency revealed its findings in their Mortality and Morbidity Report, which explains why pools are ground zero for bacteria. Between 2000 and 2014, the CDC traced 493 outbreaks and over 27,000 cases of illness that could be connected to exposure to a public pool. The primary culprit was Cryptosporidium, a parasite found in feces that causes intestinal distress. The determined little bugs can survive for up to seven days after encountering the CDC’s recommended levels of one to three parts per million (PPM) of free chlorine. Even if the pool is being cleaned and maintained properly, Cryptosporidium can idle long enough to infect someone else. The report also indicated that Legionella (which causes Legionnaire’s disease) and Pseudomonas (responsible for ear infections and folliculitis) were found in some of the pools.

The problem is likely the result of swimmers entering the pool while suffering from an upset stomach and leaving trace fecal matter behind. The CDC recommends that you not enter a public pool if you feel unwell, that you ask for a pool inspection report if you’re concerned about the hygiene of the facility, and that you absolutely not swallow any water. The agency also recommends that any pool owner who has experienced a “diarrheal incident” in their water opt for hyperchlorination to kill bacteria.

The Unkindest Cut: The Chainsaw Was Invented to Assist With Difficult Childbirths

There’s always a price to be paid for innovation. Usually that amounts to some sleepless nights and lots of trial and error. But sometimes it means attempting to deliver babies with a chainsaw.

This dark chapter in agricultural history comes from Popular Science, which recently detailed how the motorized cutting tool populating Home Depot shelves came to be. In the 18th century, two Scottish surgeons named John Aitken and James Jeffray devised a solution they could employ when faced with difficult childbirths. Rather than use a knife to widen the pelvic area by slicing through cartilage and bone to extricate a stuck baby, the two developed a chainsaw to make cutting easier.

While this sounds ghastly, the doctors were actually trying to lessen the agony endured by women who needed their pelvic bone separated. The knife took a long time, while their device—a modified knife with serrated “teeth” on a chain—could cut through bone and tissue more quickly.

If circumstances warranted it, the doctor would grab the saw, which had a handle on both ends, and wrap the chain around the pelvic bone, pulling each handle so the chain would cut into the bone. Later, the device was outfitted with a hand crank. Thanks to this innovation, difficult births could be described as merely agonizing as opposed to extended torture.

The procedure was dubbed a symphysiotomy and remained in use in the medical field as surgeons noticed how efficiently it could work in other circumstances, like amputations. It lasted through much of the 19th century as part of a surgical toolbox until C-sections grew in popularity. In the 20th century, the principle was commandeered for less disturbing purposes like logging, with two-person saws weighing more than 100 pounds each. By the 1950s, those gave way to lighter models.

For all its discomfiting history, at least the chainsaw proved to be useful—which isn't something that can be said for all inventions purporting to aid in childbirth. In 1965, George and Charlotte Blonsky patented a device that acted as a human turntable, spinning so quickly it might induce the patient (or victim) into delivering their baby via centrifugal force.

Kane Tanaka, World’s Oldest Living Person, Just Celebrated Her 117th Birthday

Less than a year after being named oldest living person in the world, Kane Tanaka has reached a new milestone. As Reuters reports, Tanaka celebrated her 117th birthday on January 2, 2020, extending the Guinness World Record-winning streak she set in March 2019.

Kane—the seventh of eight siblings—was born on January 2, 1903 in Fukuoka, Japan. She married Hideo Tanaka in 1922, and the couple had five children. Today, she is a grandmother to five and a great-grandmother to eight.

Tanaka celebrated her birthday at the Fukuoka nursing home where she resides, surrounded by friends and family. After taking a bite of her birthday cake, she reportedly said, “Tasty, I want some more." On a typical day, Tanaka spends her time studying math, practicing calligraphy, and beating the nursing home staff at board games.

The 117 club is an exclusive group only a handful of women has entered in recent history. In the last few years, Emma Morano of Italy, Violet Mosse Brown of Jamaica, and Nabi Tajima and Chiyo Miyako of Japan all reached age 117 and were each the oldest person alive for a brief period. If Tanaka celebrates another birthday next year, she will be the first person since the 1990s to live to 118.
