It’s not difficult to imagine a world in which our lives are run by digital devices. I mean, don’t we already live in one? 😉 But imagine a world where it has been taken to a new level. What if you could go beyond creating an online profile and allowing the computer to match you to an ideal mate? What if you could actually have a device implanted in your wrist that would pick up on natural attractiveness to one other by measuring things such as hormones and heart rate? The guess work and online flirting would be cut out because you would know just by passing someone in the street if they were as attracted to you as you were to them. In The Promise She Made, that device exists and it’s called LoveBite. When someone nearby finds you attractive, the device picks up on it and you get “bitten”.
