It's hard to believe that 1973 was 50 years ago. As somebody who was not alive during the 70s, that feels unbelievable. Like many Millennials and Gen Zers, I use the year 2000 as a jumping-off point for assuming how long ago a decade was. For instance, the 70s were 30 years ago, the 50s were 50 years ago, and the 90s were a measly ten years ago, right? Unfortunately, time has kept marching on, and we're almost 25 years away from the dawn of the new millennium.
There are so many things about the 70s that young people have no clue about. Sure, we might know The Rolling Stones and The Godfather, but we are really ignorant of the cultural nuances that a kid growing up in the 70s could never forget. If you made an ashtray for your family members in art class and know who The Banana Splitz are, these 70s memes will be a deep cut.
