Changing the Clocks

On my morning news trawl I came across the story of a couple who have lived the last six years on British Summer Time. They no longer alter their clocks in Spring and Autumn. It began as an experiment to see if it would help tackle a medical condition, and they insist it works so well they've stuck with it. I find myself doubting. It sounds good, and as someone who finds the time change infuriating, not to mention pointless, I should be all for it. But how could you realistically live your life an hour ahead of everyone else?
I suggest we all just drop the whole nonsense of changing the clocks and keep the whole country in summer time all year round. And don't give me that rubbish about changing the clocks to give us more hours of daylight - the sun doesn't stay in the sky longer because we change the time. You get the same amount of day, just an hour earlier, which means night arrives an hour earlier. I've never worked out how that's supposed to be better.
