It would be very reassuring to find it .. bit like reading Emma's book .. it's closer somehow. It's also nice to know what you're talking about!!! lol .. rather than some study somewhere. Still, better to know that it's there than not know at all I guess. Haven't noticed anything coming up about a study that could be worrying so I guess it's all still going on .. just as a study it's not new enough to have much written about it at the moment I guess.

Will carry on trying to find it though. Hopefully I'll remember other things I was reading when I saw it which might help Googling for it.
