I seen a documentary a few years back where college age kids had taken it upon themselves to travel the country interviewing the last remaining WWII vets to have their history recorded.
When I was working in DC with a lot of elderly people, they would often tell little snippets of their lives. I wanted to hear everything, but except for one woman who had wound up in one of Hitler’s camps, most of them didn’t really want to reminisce too much. Things would come out here and there, but they didn’t want to be ‘recorded’.
