40 years ago, people assumed we would be wearing space-y Jetson like outfits and driving flying cars. Everyone assumed we'd still be in that ever so fast-paced cycle of change where we barely glance back at the decades before us. With apps like Depop and thrifting on the rise, a new generation has begun to appreciate what those have left behind for us to cherish. From TV shows to fashion, everything from the 70s and 80s to the 90s and Y2K are coming back with a smack that'll leave your brain red. In ten years from now, we'll all be saying "Remember when we lived like we were in the 90s?". I can guarantee it - not that I'm complaining.

The biggest mystery remains: how and why have nostalgia taken over? From the latest fashion trends to kids wearing "Sublime" and "Grateful Dead", it almost feels sometimes like I went back in time to look at everyday life. Take away all smartphones and I'd really be there. My theory is that humans long for nostalgia. We crave something that we can't get back, always feeling the need to obtain the past (simply because we can't). Most stores even sell vintage-like things. Shows like "Stranger Things" give a feeling no one can understand unless you lived through it, leaving many of its younger fans hungry for more, starving for a world they missed out on. The same feeling lies within "Friends" except it feels more encapsulated in those shows than anything leaving high schoolers and college students a hint of a world they long to experience.

Personally, I have always craved the past. When I was a kid, I wanted to be a paleontologist (okay, Ross). I then wanted to study archaeology. Watching the history channel was my favorite - almost as much as playing with my mom's 1980s Barbies while watching "The Andy Griffith Show" or listening to Madonna and Paula Abdul on my MP3. Nostalgia is basically my parent and reliving the past is what I'm best at. I worry that it's become a fad, but the past will always be something I feel people gravitate towards. It gives them something to reminisce and equally wander about. It's why we love rewatching "Saved by the Bell" and "Full House" or blasting Ice Cube in our car speaker.

For now, I will just happily wait for Lizzie McGuire to return back to me with open arms on Disney's new streaming platform. I happily welcome the nostalgia - no matter what it is that brought it back.
