Thanks everyone. My dad is much better, I spoke to him this morning my time (night time for him). He has now been diagnosed with emphysema. So I need to start planning a trip home, he may have many years left, but it is such a complex condition with no guarantees that I want to go back sooner rather than later. Unfortunately England and Australia are not close, it takes 24 hours minimum to get there, but a daughters gotta do what a daughters gotta do.
