According to the CTIA, a wireless trade organization, there were 1.8 trillion text messages sent in 2009 by US mobile device users. That figure represents nearly 6000 texts for every person in the country. However, since I don't text – the figure can slightly be downgraded. On the other, all indicators are that the rate of texting has increased over the past two years. Of that 1.8 trillion, one can only imagine how many times “what's up?” was digitally conveyed.
Before I proceed I will make the customary concessions. There are, of course, sensible and practical applications of this new-fangled technology. There are instances when a timely message cannot be received as a voice communication. A message sent by a phone can serve the same function as an email or a mobile device can tie into the internet and send an email. Unfortunately, in a decade or two we may have additional data available for the study of carpel tunnel syndrome.
