I mean, it’s not age. I just don’t follow celebrity news or listen to rap. I could name maybe three rappers. Don’t listen to country music, could name maybe one performer there. Couldn’t name any Indian music performers, to pick a random genre. Or K-pop. Or folk music.
I might have a better shot at some rock or electronica musicians, at least band names, but I couldn’t tell you anything about their personal lives.
EDIT: Well, I guess…let’s see now. Elvis, Michael Jackson, Kurt Cobain, guess I could rattle off that they had untimely deaths that drug use contributed to. Elvis gained a lot of weight, Jackson had serious issues from plastic surgery. Picked that up from retrospectives or obituaries at or after their deaths, though. Beethoven was deaf.
I couldn’t tell you anything about the lives of celebrity professional sports figures either, though I know that there were many dramas that made the sports news over the years and I’m sure that there were no shortage of people who did follow them.
