Things I learned lately 30 July

• Despite its widespread use in the plots of TV shows and movies alike, a chloroform soaked rag is a terrible way to render someone unconscious as it takes around five straight minutes of breathing chloroform in via a rag to knock someone out—not the mere seconds portrayed in TV shows and movies.
• Polar bears are so incredibly good at retaining heat energy that they’re practically invisible when photographed with infrared film. The only heat signature they have is the puff of warm breath leaving their mouths.
• Canola oil is a contraction of Canada and “ola” (meaning oil, low acid). The plant it is extracted from was developed in Canada and is one of their most profitable crops.
  
  
  
• Toto's 1982 smash "Africa" has finally reached its logical conclusion with a multimedia artist's new sound installation, which plays the song on loop deep in the coastal Namib desert. Namibian-German artist Max Siedentopf installed 6 speakers placed atop individual plinths and attached to an MP3 player that contains only the song. The art piece is powered by solar energy with the promise that it will run "for all eternity."
• In 1928, at age 16, Elizabeth "Betty" Robinson Schwartz became the first woman ever awarded an Olympic gold medal for track and field. In 1931, she was in a plane crash and mistakenly identified as dead. She was placed in the trunk of a car and driven to the morgue where it was discovered that she was in a coma, but alive. It took her years to walk normally again. She couldn't kneel for a typical 100m run, so she joined the US relay team and won gold with them in 1936. Badass. 
• 11 years ago, Microsoft held a mock funeral for the iPhone on its introduction of the Windows phone. That aged well.
• Jimmy Carter is the longest-lived president, the longest-retired president, the first president to live forty years after their inauguration, and the first to reach the age of 95.
• The east end of Bowness Road in YYC starts at 37th Street NW because at one time, Calgary's city limits were at 37th Street. 
• Calgary's neighbourhood south of downtown called 'The Beltline' is named after a streetcar route #5 that ran like a conveyor belt in a loop.
• There's a Refugee Olympic team!
