“When you transition from selling something from a physical product to a digital product,” Shiller explained, “it allows the seller, the publisher to restrict resale, they can prevent you from reselling the item, and that ends up being very profitable, particularly for the types of goods that people grow tired of.” This suggests that companies selling these goods have a strong incentive to find ways to distribute products where people can’t resell it, with digital distribution a great way to accomplish this. Resale markets tend to disappear in these markets as a result, he added: “I think it’s more hidden rather than acknowledged.”

Your body is built to wake naturally with the sunrise and feel sleepy as the sun sets. The light at both the beginning and end of the day is a warm, golden tone, unlike the midday bright, slightly blue sunlight that keeps you wide awake. A sunrise alarm clock mimics this transition from morning to bright daytime light, helping to signal your body to wake up (or fall asleep, if the clock also has a sunset option).
