Hi there Rain,
I was born in 1923,and have heard so many of these predictions!
Every 10 years or so people predict the end of the world.
If the end of the world ever does come,I think it will be with a cataclysmic bang,and we won't get any warning.
Most of the doomsayers are people addicted to numerolgy,who think they can predict the future by working it out from numbers.
Well, they haven't been right in the past,and I don't think they will be right in the future either.
So don't worry.
