This is mainly for the middle-aged and beyond. Most people who have already reached a certain age will know that as you get older you see people who were always around as you were growing up start to die and it leaves a little hole in your childhood memories. There's also the fact of starting to contemplate your own mortality (except SJS who will never die).
It doesn't only apply to cricketers of course but this is a cricket forum so the demise of which cricketer do you think will hit you hardest?
The recent deaths of Tony Greig and Christopher Martin-Jenkins came close for me, but I think if I manage to outlive Clive Lloyd his demise will be a particular sad day. As a fan of Kent and England the passing of Derek Underwood and Alan Knott would also be very solemn moments.
