International human rights day (10 December) marks the anniversary of the United Nation’s historic “Universal Declaration Of Human Rights” on 10 December 1948. The UDHR set out for the first time in a single document the fundamental rights to which everyone, everywhere is entitled - including the right to life, liberty, security, the freedoms of opinion, association and expression, and the right not to be subjected to torture or cruel, inhumane and degrading treatment.

‘‘Chase the Tear’’ is a reference to a paper tear-style “tear”, not a tear from an eye!
