Things I learned this week 11 Nov

• A regional airline pilot might only make about $16,000 in their first year.
• Of the top 20 American cities leading in foreclosures in August 2012, 10 were in California and 6 were in Florida.
• Only 1% of us are redheads, but 4% of us carry the gene that makes redheads. You could be a carrier and not even know it. Two brunettes can make a redhead. Good luck wiping them out.
• Jon Favreau, the director of Iron Man, based his version of the character (played by Robert Downey Jr.) on Tesla owner Elon Musk.
• The total amount of gold ever mined would only fill 1/3 of the world's largest supertanker. It would fill about 120 standrd shipping containers. What's all that gold worth? $8 trillion.
• The top 10 richest people in the world are collectively worth $395.4 billion.
• Thanks to his two year contract extension, David Letterman is now the longest serving late night host on television.
• The highest paid TV star is Judge Judy Sheindlin, at $45million per year.
• Elon Musk quote: "Boeing just took $20 billion and 10 years to improve the efficiency of their planes by 10%. That’s pretty lame. I have a design in mind for a vertical liftoff supersonic jet that would be a really big improvement."
• For every 15g of edible meat, you need to feed animals around 100g of vegetable protein, an increasingly unsustainable equation.
• A door-to-door bookseller also gave away perfume gifts, which became more popular than the books, that motivated David McConnell to switch to selling the perfume and the California Perfume Company was born, which later became Avon.
• William Wrigley Jr. sold soap and baking powder and gave away chewing gum as gifts. The gum became so popular, that he switched to selling only the gum.
