What Would the 19 Seventies Be Without, Without Decades?

What would the 19 seventies be without, without decades? You know, how would we think about that time period? What would be the barriers to it? How would we package that up? And i guess i 'm still prone to this kind of thinking. Who knows how many weill go to, but for seven days worth of episode, right? We're getting into the subject of the week and i think thi this one has a really interesting peg.
