Computer specialist Martin Leung does not come over as a worried person. But he says he will not fly on December 31, 1999 - in case the plane crashes.
'Every year my wife and I normally fly back from the States on December 31. But not in 1999. That year we'll leave it about a week after January 1.' In fact, he suggests the safest thing for everyone to do that Saturday morning is to stay at home, and that's not because of hangovers. 'Monday will be tough,' he says.
If you have not guessed, he is talking about the currently hidden trouble that may burst into frightening activity the second the millennium changes. In the jargon, it is the Y2K (Year 2 thousand) bug, the glitch that means those super-duper computers that do everything from calculate your tax to fly planes cannot recognise the year 2000.
And if you are under the impression that it will not affect you because you do not run a huge mainframe computer, keep reading.
'I know my home computer won't work. Neither will my fax machine. I've tested them,' says Mr Leung, who has the remarkable title of 'principal consultant year 2000', for computer firm Platinum Technology.
'Have you got a video recorder where you set the timer? That won't work. Does your mobile phone give the date in two digits? Then that might not work either.' And as for those handheld organisers that contain all your essential information like appointments . . .
In fact, anything that uses a timer and calculates dates to function could be affected.
