Hi janieg

Thanks for this - it may be just coincidence or a case of 'great minds think alike' but just yesterday I caught a news item on TV here (NZ) about a research project in Australia on exactly this subject.

I've tried to find a link to the news item but can't (don't have a lot of time this morning) but did find a link to an overview of the project:

I'll bookmark it and follow up later. The Charles Perkins Centre (where the study is based) looks like an interesting place for lots of research.
