I've thought about it loads esp having worked in a hospice and being with my nan when she died.
It doesn't scare me so much now, used to wake up screaming about it when I was little apparanty, esp after I was very ill in hospital and was lying there after being rushed in by ambulance (twice) and was so peaceful even though it was very painful etc... and I remember thinking it wouldn't be so bad to just slip away.
I feel better knowing some of the people I hope are there waiting fo rme when I do. Doesn't feel so scary if they're there :)
