No big story here. Nothing struck me as being particularly tragic other than the fact that the older gentleman, well dressed and well put together, was hunched and obviously getting on in years.
It did strike me that it must be much more difficult to get around a crowded city when you are older and your body has begun to significantly decline. Here he is surrounded by a crowd of much younger New Yorkers, all rushing to get past him. His slowness turns him from human peer to obstacle in their eyes -- something to be overcome.
I also like the visual effect here of the "giant" old man and the "tiny" woman offering free food samples on the right. It looks like he could just reach over and eat her head.
