i don't think it's an age thing. unless i'm mistaken, i recall this image is from WWII, and it's a Brit or Australian POW about to be executed in a Japanese POW camp. i first saw the photograph in late middle or high school, when i got super interested in photojournalism. i saw a lot of images as a kid then that were from decades before i was born that were amazing, terrible, and unfortunately stuck in my head in a not-always good way. which, is hopefully one of the finer points of good war photography. i want to say that this was a robert capa? i'm sure i'm wrong.
MY POINT is (long windedly) that it's not really age, but maybe more personality and empathetic response that makes a body react or not react to a photo like this. i'm not offended by the poster, i agree that it's a good play, however unfunny and totally fucked, on the situation captured here. RIP soldier. war sucks.
