Thanks Clare and Bea!
2 years ago I had a very bad case of flu. Thankfully, as I'd had my flu jab it only lasted three days. If I had not had it, I suspect I would have been a lot worse for a lot longer. It may not prevent me getting it but it should be a lot shorter. I had real flu, not a heavy cold, 30 years ago. I could not get out of bed for around 5 days, could not stand and felt extremely ill. If you've had flu, you will know it, it's nothing like a bad cold.....
