Having turned 50 yesterday, I'm going to be mindful of one thing; I'm going to avoid telling anyone that something was "before your time." Too often, when people say that, they're just reminding you that they've been around longer than you have. Instead, I'll say something like, "So-and-so had a lot of hits in the '70s," or "(S)he was in such-and-such a movie or TV show..."
That's just courteous, I think.
