Just because there are 24 hours in a day doesn't mean you have to use them all. Tell that to Tory leader David Cameron: in the final days of the campaign, he traversed the U.K. nonstop for 24 hours, in a journey that included beating the volcanic-ash cloud to give a speech in Northern Ireland and visiting a fish market in the early hours of the morning in Grimsby. It seemed that yet again, Britain had turned to the U.S. for inspiration, as Al Gore is widely credited with ushering in this trend when he went a full day without stopping in his ultimately unsuccessful bid to become President in 2000.
