Alas I'm way busy with work at the moment to make a contribution to this discussion of any significance.
But on Friday, when I bought a red ribbon from folks near the railway station, attached was a small card that said, among other things, '95% of people living with HIV reside in the developing countries'
Can't remember which, but some African countries now have an average life expectancy of about 40.
If nothing else, it was at least heartening to see quite a few red ribbons being worn on Friday.
