And if you give a Gen XPeople born between 1965 and 1980.-er a chance to show off their moves to the songs of their own youth, they may yet surprise you.

That is what thousands of TikTok users have discovered as a new trend sweeps the platform. In the videos, children put on '80s songs and ask their parents how they would have danced to them back in the day, only to be bowled over by a phenomenal disco display.

So why do these little moments of dance bring us so much joy? And could it be the secret to human salvation?

Dance is probably the oldest human art form. Cave paintings in India dating back 30,000 years depict people dancing.¹ Dance would come to be associated with the HinduA follower of Hinduism, the third-largest religion in the world. Roughly 95% of Hindus live in India. god Shiva, whose dancing destroys the universe and causes it to be reborn.²

Indeed, dance has always been important for faith. In ancient EgyptOne of the most powerful civilisations in the world's history, lasting for more than 3000 years between 3150BC and 30BC. , dance was an important part of religious ceremonies.³

The ancient Greeks had their own god of dance, Dionysus, who was an emblem of wild human passion and creativity, against the order and rationality of his counterpart Apollo.

In Europe, dance became a central part of social life from the 18th Century. Young men and women would attend balls and dance with prospective partners.

Why does dancing have such a universal appeal? Philosophers think it is because it perfectly expresses what it means to be free.

Human freedom is the same. It only works if we follow a set of rules, rather than our own whims, otherwise we just trample on everyone else. But we can invent and create new ideas within the rules, following our own creative impulse.

It lasted from about 500 to about 1500., chroniclers reported outbreaks of a strange and disturbing illness known as dancing mania. Completely out of the blue, groups of people would start dancing and not stop until they collapsed from exhaustion, often dying as a result.⁴

Could dancing save the world?

Yes: Dance is one of the few things that bring all human beings together. And it can show us how to live in a world where we can only be free together, not at each other's expense. To dance is to be human.

No: Dancing does not bring us together. In fact, many people throughout history have mocked, hated or feared each other for the different ways in which they dance.

Or... Dancing is fun and can even be powerful, but it will not change the world. We have to create a better world together, and only then can we dance in it.
