According to an article in Wired:
Hans Jørgen Olsen, a 12-year-old Norwegian boy, recently survived a moose attack by feigning death, "just like you learn at level 30 in World of Warcraft."
In WoW, "feign death" is a skill acquired by hunters at level 30 that allows them to take a page from the possum playbook, collapse to the ground, and convince their enemies -- who lose all ingrained animosity in the process -- that they've died.
According to Norwegian site Nettavisen , Hans and his sister apparently enraged one of the local moose (mooses? meese?) during a walk in the forest near their home. After shouting at the gigantic creature to ward it away from his sister, Olsen dropped to the ground, and presumably his lifebar plummeted to zero.
