Among the things I learned this week:
* Betteridge’s Law of Headlines states that if a headline ends with a question mark, the answer is no. (Courtesy: Matt Levine/Money Stuff)

* The absolute deliciousness of wild-caught Alaskan salmon overnighted to your doorstep. (Courtesy: DK)

* A thousandth-of-a-second in men’s world-class swimming is equal to about two centimeters of distance traveled. The swimming governing body (FINA) allows three centimeters of variation among pool lanes. It seems picking a shorter lane could yield significant results, although FINA uses hundredth-of-a-second times to mitigate this. (Courtesy: Tim Burke/Deadspin)
