The second brake is a little different. It’s more like the hand brake in a car, a chronic, low-level “No thank you” signal. If you try to drive with the hand brake on, you might be able to get where you want to go, but it’ll take longer and use a lot more gas. Where the foot brake is associated with “fear of performance consequences,” the hand brake is associated with “fear of performance failure,” like worry about not having an orgasm.
