Interesting story on the BBC:
BBC Online - Big day 'can't slow cancer death'
Interesting as I've examples in my life of instances where relatives have hung on, or appear to have died on a special day. I suppose it's a case of the emotion of the occasion muddying the facts perhaps, but it's still uncanny that, on knowing we'd all be around on a particular weekend, or a special day was coming along, that the loved one in question passed away. Despite the results of this research, I still believe that people can wait, determine the end themselves.
As an aside I stumbled across this part of the general BBC site:
bbc.co.uk - Relationships - Coping with grief - - Homepage
Worth a read, if only to get an insight into what to expect, and why you feel the way you do.
