The stories of heroism are starting to filter through now from the horror in Tunisia at the weekend and they are breathtaking and poignant. And so, so heartbreaking.

Their acts were spontaneous and selfless and none believed, when booking their holiday in the sun, the label “hero” would soon be attached to them.

Heroism takes many forms but this is the one I am sure no-one wishes to be tested on; the instant, life or death form, the one that over-rides your fear and your instinct for self-preservation.

For the survivors of this, and the countless other atrocities and disasters around the world, comes the next challenge; to survive being a survivor; a heroism in its own right.
