Thank you everyone, I have COPD and I thought I was being over silly when I kept saying to people please stay away from me if you have a cold. People also think I am being daft , but after reading lots of different posts I now realise I am not being silly.
My problem is I also have a low immune system, but I always go down after everyone else, they are all coming back better .
I work in a call centre with air conditioning so not good
but thank you all
