  1. Tim Harford sings praises of gaming:
    “But for most gamers the point of games is that they are enjoyable in a deeper way than most mere entertainments. They create moments of enchantment to rival the finest music or theatre. A good game has you solving puzzles, throwing yourself into improvised acting, and then helpless with tears of laughter. The friendships I’ve forged over the gaming table have been the ones that have lasted.”

  2. On living in a commune in San Francisco. Beer isn’t welcome anymore, apparently.
    “I made my first mistake early on. It came at one of the dinner parties, which tended to happen spontaneously: one person would sit down quietly to eat a stir fry, before others joined them with takeout or leftovers. I brought a case of beer, which seemed to offend the zest for self-improvement that defined the commune. Sleep, and getting enough of it, was the topic du jour. Entire dinners were spent discussing the finer points of sleep tracking, which monitoring gadgets worked best (the Oura Ring was popular); how best to optimise a bedtime schedule; what to eat; what not to drink. I felt like a Neanderthal, supping beer and interjecting to add that surely it was important to enjoy yourself now and again. This sat oddly with a group that was on a different path towards self-actualisation. Alcohol disrupts sleep, it turns out.”

  3. A fascinating article on… feathers.
    “Feather stuffing, once the height of luxury, has become ubiquitous. Over the past quarter-century, our global demand for warmth – even on a short shopping trip – has led to a tripling of the global trade in feathers by volume. Never mind being light as a feather, the raw plumage that drifts across borders each year is equal to the weight of nearly 90,000 cars. And 80% of those feathers come from one country: China.The trade in feathers is not a simple case of supply meeting demand. The down in our coats is, in fact, a by-product of the ducks and geese that end up on dinner tables. In terms of price per weight, down feathers – the soft, fuzzy ones on the bird’s breast – are the most valuable part of a duck, worth $25-50 per kg, roughly ten times as much as the meat. But a typical bird yields some 2.5kg of meat compared with just 15 grams of down, so a duck’s value lies mostly in its flesh. The soft feathers account for just 3% of its value, so abattoirs see those fluffy hairs not as a treasured commodity but detritus.”

  4. Curbed chooses bike sharing as the biggest thing to have happened in the previous decade.
    “Studies have shown that bike share can help boost some transit ridership and may even be safer than riding personal bikes. The average cyclist death rate is 21 deaths per 100 million trips, but through 2014, after seven years of bike share in U.S. cities and 23 million rides, not a single person had been killed riding a bike-share bike. By the time U.S. bike share rides hit 100 million, which happened sometime in early 2017, only one death had been reported.”
