I think probably what I fear is something ghastly happening to my very closely-knit family, my sons, their wives, and my grandchildren.
I fear the world is not a safe place for youngsters to grow up in and I fear that the kind of world I knew when I was a child is possibly never going to be seen again.
My greatest fear is that they won't have as happy a life as I hitherto have enjoyed. And that makes me very frightened.
