Find the variable you can control, à la @rorysutherland: e.g., more effective/cheaper to make trains comfortable than reduce travel time. It's easier to increase exercise time (~10h/w) than punish yourself w/food deprivation, particularly if you like good food & delicacies. https://t.co/6MIMgBt0M8 — PolitiTweet.org
