A girl is snowboarding --- Unaware that "someone" is chasing her!

While browsing the Internet, we often come across tales of spectacular situations and events, but we cannot always be sure of their truthfulness. 

In this case, we observe a scenario that definitely keeps us in suspense! A girl is preparing to go snowboarding while using earbuds to listen to music, consequently, she does not notice that she is being followed by a bear that is running furiously trying to catch up with her! 

The video, though actually very realistic, has raised many doubts. What do you think?
