What Goes Up....

Not that I'm normally one for paying too much credence to pub conversations, I did hear something quite disturbing last night.
Apparently, and contrary to what I've always believed, it is actually possible to catch Down's Syndrome, under certain circumstances, from the age of about thirty, onwards!
Being one of those people who's lives are ruled by 'certain circumstances', I was worried enough to research the matter as soon as I got home.
The fact that I couldn't find any reference to this, anywhere on YouTube, just smacks of a big cover-up and has deepend my concerns exponentially.

In fact, all I could find was this video and, to be quite honest, apart from being no help at all, I also found it a quite offensive!





Is there a doctor in the house who can clear this up?
