- The Men Who Stare at Screens (NY Times) — What was unexpected was that many of the men who sat long hours and developed heart problems also exercised. Quite a few of them said they did so regularly and led active lifestyles. The men worked out, then sat in cars and in front of televisions for hours, and their risk of heart disease soared, despite the exercise. Their workouts did not counteract the ill effects of sitting.

- Caring with Cash — describes a study where “pay however much you want” had high response rate but low average price, “half goes to charity” barely changed from the control (fixed price) response rate, but “half goes to charity and you can pay what you like” earned more money than either strategy.
