When we mechanized time, we also, and completely by accident, mechanized us. And when the clocks got smaller, time could follow us everywhere, a constant reminder of hours, minutes, seconds lost or won. Now we don't eat when we're hungry, we eat when it's time to eat. We don't sleep when we're tired, we sleep when it's time to sleep. We've built an amazing world that runs like clockwork, meaning that these days, so do we.
