Thankfully, someone thought to record their impromptu dance party and share the video online for the world to see. This is proof that age is just a number and it's important to keep yourself moving, no matter how old you are!
The Your Care Everywhere website explains that dancing has a wide variety of benefits for those who are feeling the effects of aging. The physical benefits are obvious - moving around for a few minutes each day can build muscle, keep your core active and your heart healthy.
In addition to the physical advantages, the mental and social aspects of dancing are important as well. A sedentary lifestyle is one of the things that can make getting older miserable, and dancing is an easy solution to boredom.
If you have the chance to join a group dance class, you can make friends, giggle and boogie along with other people who want to stay active later in life. These reasons are probably what prompted Grandpa to dance along with his sweet granddaughters.
