Two things

Big fad currently seeping into London - the mini-Segway hover board. First time I saw them two men were on their way out in Shorditch (one assumed from where they were) gliding down the road in hats holding umbrellas against the rain. Then next there was a group of seven youths all riding them down the street in Peckham in a range of colours. Yesterday a woman using one along my street at home. These are electric powered boards to assist walking. It isn't as fast as a bike. And it costs nearly £300. The 'riders' stand bolt upright and still (it appears). It's not about tricks (like a skateboard). And it isn't going to transport you for long distances. So I'm guessing in the future when we all need them we will increase our obesity through lack of needing to walk. 

And then, one hopes, that soon we will get a surgence of 'old style' cafes where it is deemed inappropriate to be using a computer or linked into a screen all the time. The cafe opposite work today was filled with single computer users drinking cups of tea (cheapest item on the menu) at each table. A request to share a table was met with a shrug and when my colleague arrived to drink coffee with me the table 'owner' huffed off elsewhere. Perhaps small cafe owners will tire of providing free electricity and wifi and try to get back to encouraging socialising...
