Back again ... away again

I'm back again - a month gone by, during which I had an obituary for the King of Tonga published in the UK national daily, The Guardian (www.guardian.co.uk/obituaries/story/0,,1876280,00.html), and had a weekend in Berlin. Next week I'm off again, this time to Ottawa and Toronto, for more work with the Canadian Health Services Research Foundation, and a conference run by them in Toronto. It will be my third visit to Canada in the past twelve months.
