If you have a digital recorder (formally a tape deck) you can record a parent, aunt, uncle, grand parent. My niece, my sister and I asked my father a year before he died just about everything about his life. It was a good thing that we did. We have it included in his biography.
It is true that you will get some pretty wild tales as the colorful life becomes more colorful as the body ages. I personally added science fiction and fantasy to my biography.
