It's the start of a new year, which means it's time for some very important rituals. It's time to make resolutions. It's time to look forward to the promise of a fresh slate. And it's time to feel really old.

This article is here to help with that final point – but at least with the help of a killer soundtrack.

Last month, DJ Rhett posted a Facebook video compilation of great classic songs that all have one thing in common: They're all turning 40 years old this year. That's right: Songs like "Jessie's Girl" and "Celebration" are now that much closer to qualifying for their AARP cards – though, honestly, they're nowhere close to over the hill. (Kenny Rogers' "Lady," on the other hand ... sorry.)

Here's DJ Rhett's full clip:

That's not even close to all of the songs turning 40 years old this year and making you feel the cruel passage of time! 1981 also brought us "Physical," "Don't You Want Me" by The Human League, "I Can't Go for That (No Can Do)" – though Hall & Oates is represented in the above clip – and the theme song to "Chariots of Fire." How did people dramatically run in slow motion before that!? It also marked the last year anybody could have the phone number 867-5309 without losing their sanity. What a time! 

For more flashback fun, the following movies are also turning 40 years old this year: "Stripes," "Cannonball Run," "On Golden Pond" and a small little indie film called "Raiders of the Lost Ark." 

Anyways, here's to a new year, and here's to these songs and movies that have miraculously stood the test of time – and will probably survive another 40 years. I mean, they better. I don't want to live in a world where people are throwing parties and big happy events without "Celebration" by Kool & the Gang.
