David Sedaris racconta sul New Yorker quello che succede quando comprate un activity tracker, come il Fitbit:
I was travelling myself when I got my Fitbit, and because the tingle feels so good, not just as a sensation but also as a mark of accomplishment, I began pacing the airport rather than doing what I normally do, which is sit in the waiting area, wondering which of the many people around me will die first, and of what. I also started taking the stairs instead of the escalator, and avoiding the moving sidewalk. […]
During the first few weeks that I had it, I’d return to my hotel at the end of the day, and when I discovered that I’d taken a total of, say, twelve thousand steps, I’d go out for another three thousand.
“But why?” Hugh asked when I told him about it. “Why isn’t twelve thousand enough?”
“Because,” I told him, “my Fitbit thinks I can do better.”
