If, like Rip van Winkle, I'd fallen asleep 30 years ago (1981) I'd now be waking up and marvelling at all the things which have changed.
Mobile phones. Handheld computers. Multi-channel TV. Marathons are now called Snickers.
Yet so much is the same. Tory Government (sprinkled with a few 'Wets' to provide minimal reassurance). Cutting back to 'pay our way'. A pointless foreign war. Weak political opposition. Disaffection and destruction in our cities. Violence directed towards police and property. Young people wrecking their own communities.
But the most extraordinary is that this time the riots begin in London ... Not in Liverpool.
Now that's worth thinking about.
