As government agencies and tech companies develop more and more intrusive means of watching and influencing people, how can we live free lives?
I knew we’d bought walnuts at the store that week, and I wanted to add some to my oatmeal. I called to my wife and asked her where she’d put them. She was washing her face in the bathroom, running the faucet, and must not have heard me—she didn’t answer. I found the bag of nuts without her help and stirred a handful into my bowl. My phone was charging on the counter. Bored, I picked it up to check the app that wirelessly grabs data from the fitness band I’d started wearing a month earlier. I saw that I’d slept for almost eight hours the night before but had gotten a mere two hours of “deep sleep.” I saw that I’d reached exactly 30 percent of my day’s goal of 13,000 steps. And then I noticed a message in a small window reserved for miscellaneous health tips. “Walnuts,” it read. It told me to eat more walnuts.
