Being a youtube junkie, I often stumble across all sorts of stuff. I came across this ivideo which really had an effect on me. It's just a collection of World Press Photos of the Year from 1955 - 2008. It's worth a watch if you have the time. For many it will bring back memories for others it will show events in history that they may not have been around for. Just powerful stuff. Turn the odd music down a bit and it will fade in the background as the pictures power takes over. Make sure you go full screen to see the pics.
I got to the above collection through this video from 1963...
