South Korean soldiers stationed at the Demilitarized Zone (DMZ) have the stressful job of guarding the border between two nations technically at war. Though North and South Korea have signed a truce, the countries are considered ‘at war,’ as no peace treaty was signed after the 1950-1953 Korean War.  

To help soldiers deal with the pressure, the South Korean army has started offering ballet lessons. In the video above, soldiers talk about how ballet has helped them relax.
