Just watched a dvd of the the old movie, On The Beach , with Gregory Peck. I've seen it before but not for many years and it made an impact on me then and again this morning. It's a brilliant movie even though it was made in 1959 and was black and white.
For those that don't remember it , told of the consequences of radiation dust tracking across the world killing mankind off until the only place left was Australia and how the people dealt with
This ever present threat if us all being killed off either by radiation or virus is never far away. Very sobering thought!
