Things I learned lately 3 Feb

• Americans flock to Los Algodones, a Mexican border town, to get dental work done on the cheap. A crown goes for USD$300. There are 350 dentists working in this town. There 5500 people living there. Los Algodones also has numerous plastic surgeons, optometrists and pharmacies.
• Chocolate is under threat from climate change. Cacao plants can only grow within a narrow strip of rainforested land roughly 20 degrees north and south of the equator, where temperature, rain, and humidity all stay relatively constant. Over half of the world's chocolate comes from Côte d’Ivoire and Ghana. But these areas won't be suitable for chocolate in the next few decades due to rising temperatures.
• Statistics Canada's figures indicate more than 21% of Montrealers can speak at least three languages, compared with 11% of Torontonians and 10% of Vancouverites.
• If you intend to upgrade to a 4K HDR TV, your existing 1080p video switching receiver may not be compatible. It needs HDMI 2.0 for standard 4K, HDMI 2.0a for HDR content, and HDCP 2.2 to play along with the new copy protection scheme.
