Today's quotable quote: Tom Lehrer: In my youth there were words you couldn't say in front of a girl; now you can't say “girl.”

This day in history: 02 December 2022: Benazir Bhutto Becomes First Female Leader of a Muslim Nation (1988). The daughter of a Pakistani prime minister executed following a coup, Bhutto was keenly aware of the risks of political life. Nevertheless, she chose to follow in her father's footsteps and in 1988 became prime minister of Pakistan, becoming the first woman to lead a Muslim nation. Dogged by allegations of corruption, she fled the country in 1999. She returned in late 2007 and, after escaping one attempt on her life, was assassinated.

Doctor Anna's Imaginarium

//If you’ve seen manatees up close and observed them for a while, no doubt you’ve seen some bubbles nearby. Sea cows often release gas as a part of their daily routine. But, from a scientific standpoint, there is research that shows manatees can control their buoyancy from farting. They use their digestive tract and the unmistakable flatulence they exhibit as a way to rise and sink in the water. But how does a fart make a manatee go up and down? Well, the sea cow can “hold it in” and that gas makes them a little lighter helping them to float near the surface. Or the manatee can “let it rip” releasing some gas and sink a little lower in the water. This releasing of gas isn’t like a jetpack on their back, zooming them to the bottom. But it does help them to slowly sink lower towards the bottom.// ... But they also have specialized lungs ..
