I say things like this, too.
And then I have to remember that the 70s was forty years ago, and will soon be 50 years ago.
To put that into perspective, if you were a kid or a teen in the 1980s, it would be like someone telling you that "The 1930s really weren't that long ago, what, with the Jim Crow laws, and the no televisions, and the black and white movies, and the having no idea what World War 2 was because there was only the Great War ...."
Man, getting old sucks.
Wasn't that "The War to End All Wars"?
