Predictions are usually based on current trends or information. But life is dynamic. There are many unforeseen developments that negate the predictions. Quite often even the weather forecasts go wrong.

I agree with Gulshan..often weather forecast is wrongly predicted..If they say it will rain heavily and thick clouds will cover the sky..some think quiet opposite will happen like sunny day with very hot temperature... :)
