　　In earlier times, both diet and attention could be left unregulated(没人管的)without major cause for concern. There were natural checks and balances: limited availability of food meant few got fat, for example. Similarly, in bygone times we might have spent a few hours communicating with the village storyteller, today, watching an entire TV series, while speaking to nobody, is common. In traditional societies, with smaller population, everyone would get a fair deal of attention. On many issues we might go to see Grandma or Grandpa; now we have Google and Wikipedia.

　　“She just wants attention.” people tend to think little of those doing things simply for attention. But the truth is that human beings need attention, and giving attention to each other is, to a large extent, what human civilization is based upon. This perhaps explains the runaway success(一举成功)of social networking sites such as Twitter and Facebook. While we use such sites for “micro blogging”, “idea voicing” and “status updates” – the reality is that we are often doing no more or less than fulfilling our basic human drive for attention exchange.

　　I friend you, you friend me, I retweet you, you retweet me. The charming case with which we can now get and give attention is why many people appear overly attached to their smartphones. It is also a vicious(恶性)circle. As ever more people are busy exchanging attention online, there is increasingly less attention to be paid in the real world, which forces more people to seek their attention exchange online, or else risk attention-starvation.
