GREY TSUNAMI

In this century the world's population will grow
dramatically older. This second episode takes us
into the lives of people across the world already
impacted by the inevitable march of global ageing.
In China elderly people in the countryside are left to
fend for themselves as families shrink. In Australia
the so-called 'sandwich generation' finds itself
trapped between caring for both grown up children
and frail parents, with no prospect of ever retiring.
