Fall of British Empire Caused by Cheese Rolling?

An empire, by definition, is simply raw power, typically via the control of wealth and resources by a very small group, that unjustly places a burden on the populace for the benefit of those who own that control.

The decline and fall of the British empire can be attributed to many factors - greed, poverty, denial of basic human rights - that resulted in a populist backlash.

Or it could be that the British are brain-damaged from their traditional cheese-rolling. I'm not an anthropologist, so I'll let the video speak for itself.
