Friday marks the ninth annual World Down Syndrome Day -- the third since it became officially recognized by the U.N. -- and some are celebrating with a spring in their step.
Watch the "Happy" video above, which was posted to YouTube on March 19 in honor of the occasion, and in which pure, unbridled joy takes center stage.
But the day has a serious side, too. Down Syndrome International is using this time to remind everyone that Down syndrome "does not make a person unhealthy" and that people with the genetic condition have the same right to health care access as others.
"Lets create a single global voice for advocating for the rights, inclusion and well-being of people with Down syndrome," the organizers wrote on their website.
We'll happily get behind that.
