Social media is surely the Internet equivalent of picking your nose, and actually interacting with social media is surely the Intenet equivalent of eating it too. In fact, I'd go so far as to say that social media has replaced picking your nose as the world's number one brainless activity. Even being asleep requires more intelligence and discrimination than "liking" a Facebook post.
Once upon a time, dragged daily through the underground vaults of the city by a rattling tram, I often witnessed google-eyed commuters burrowing into their nostrils with wormlike fingers while staring into space. These days, however, those same overworked digits idly massage the screens of Smartphones instead, their owners sniffing and snorting as they briefly acknowledge each Facebook update with a dismissive swipe.
Alas, operating a smartphone at the moment obviously requires both hands: one to securely grip the expensive device and the other to knead, slap and poke its surface. Consequently so much nasal waste remains uncollected now, like bags of slimy garbage abandoned by the train tracks, since former nostril-rummaging fingers are currently otherwise engaged.
The development of hands-free tech will no doubt provide a solution, enabling Facebookers of the future to merely blink to like their friends' latest Instagrams, leaving all their fingers free to excavate each nostril as they blink again to scroll through even more insipid images.
Such will the walls of the World of Tomorrow be smeared with squillions of both real and 'e' boogers, fresh picked from squillions of real and virtual noses.
