Hi franca. Did you have a nice time?
Dunno about swine flu. OTOH it seems frightening and confusing - especially as regards who is most "at risk". But when I reflect a bit, I think, "well, it's flu', basically... So do what you would normally do to avoid flu', e.g. wash hands, avoid sneezing people...", etc.
Yes, I think the over 65s are more vulnerable. Although younger people are more affected, presumably they are - epidemiologically speaking - healthier, so stand a better chance of full recovery. I think the most confusing part is about the under-5s, who you would think are also vulnerable; however, I imagine they are still less vulnerable than a frail old person (not saying, however, that all 65+ are frail).
I feel a bit manipulated by the media, I must admit, in terms of feeling "panicked".
