A beautiful ad from the Special Olympics is highlighting the power of sibling bonds.
Titled Born Apart , the one-minute video tells the story of twin friends. One has Down syndrome, and the other does not. As they grow up together, they develop a special relationship and pursue the same interests, like competitive running.
Over 7 million people have watched the touching video. As the captioning at the end notes: Born 4.36 seconds apart. Its the only difference between us.
