Maybe religion is the biggest con of all times.
That a significant percentage of the worlds population can be convinced that some mystical dude who is floating around in the sky is going to save them or provide them with salvation, could be seen to rank with those who believe in the tooth fairy, Santa Claus and the bloke who says the cheque is in the post.
Can't say is does anything for me, but hey if people want to believe in mythical beings to get them through the day, who are we to say they are wrong. Whilst they can't prove the sky floaters exist, I can't prove they don't!
Let's call it a draw.
(And yes I'll still call/email before an ULH flight)
