I'll be having it - must remember to make appt!
Have only had real flu once, but it knocked my stuffing right out for a full 3 weeks. Especially since I now have very little Gdcs I see a lot, one of whom has been in hospital 3 times with bronchiolitis - thankfully, touch wood, he seems to be growing out of it.
Even when I was considerably better after my dose of flu, and out with dd walking the dog, I remember her saying, 'Can't you walk a little bit faster, Mum?'
'Sorry, darling, I really can't.'
People who call a bad cold 'flu' are apt to get a very nasty shock if they ever get the real thing.
