First of all I am not talking about the winning of a Victoria Cross. For me that is bravery, you either have that or not as it emerges unbidden in extremes. Nobody really knows if they are brave until they face a clear danger head on.
Courage is subtler.
We need it every day, sometimes only in small amounts as it fuels the success and enjoyment of our days. Courage is what gets us out of bed and allows us to engage with the world and each other. It lets us believe in good and cope with bad.
Without it we would all be lost.
