It was my sister's 70th birthday last Sunday. She is twice as old as our eldest brother was when he died suddenly and tragically at just 35 and yet to me - almost 24 years older - and I'm sure to her as well, he is still, in my mind's eye, our older brother. I've spoken to many people over the years who have had an older sibling die young and they all have the same experience as they get on in years. It's really very strange. I remember the late Anthony Quinn saying something similar regarding his father, who died in his twenties.
