There's a story at the back of my mind which I wish I could remember because it illustrates what I want to say but I can't get my brain untangled enough to make it make sense.

Here goes anyway.

There are two possibilities here - either we've got a global warming problem or we haven't.

There are two things we can do - either nothing because we don't believe there's a problem, or tackle it because we do believe there's a problem.

If we tackle it and there is a problem - we may well solve the problem.
If we tackle it but there wouldn't have been a problem - we still don't have a problem.
If we do nothing and there is no problem - we still don't have a problem.
If we do nothing and there is a problem - we've got a problem.

It therefore makes sense to me to act as if we do have a problem even if it can't be proved.

On the subject of HIV I don't think I'd broadast it to any of my friends if I had it so for all I know I may have friends who are HIV positive but haven't told me either.

On the subject of Y2K - the LDS computers didn't have a problem because they all contained data going back centuries and were already programmed to deal with 4 digit years.
