From the BBC:
"The problem is really how people are getting around. They are driving more, cycling less and more likely to be employed in a sedentary job.
"Physical activity is slowly being removed from day-to-day life."
Not to pick on the Brits, it's happening everywhere, not least of course in the US of 'hey, buffet!'. I've read the Aussies have their own obesity epidemic. If only a certain magic wand (on two wheels) weren't staring us right in the face...
