The video below is going to bring a huge smile to your face, for sure. It has been going viral on the internet recently, and for all the good reasons. It features a group of 50 residents from the Julia Wallace Retirement Village who spent an entire week filming and choreographing a lip sync video to “Shake It Off” by Taylor Swift.

The performers have a total combined age of 4,000 years and an average of 82. The staff members and the grandchildren of the residents are also featured in the clip. All of them are lively and full of energy. Just looking at them makes you want to join in. If you are one of those people who think elderly citizens don’t know how to have fun, you should definitely watch this.
