There are some people you just can't force to be bothered. They're cool as a cucumber in one situation; cold as ice in the next. The people featured in this video seem like they just don't give a darn. They've mastered the mantra "Keep Calm and Carry On." They live the acronym DGAF. This is how you cool. From the battle worn soldier who doesn't flinch at the sound of nearby rockets raining down in the city around him, to the man who stands without budging in front of the charging elephant, these people exemplify how to be the chillest person in the room. Meet some of the most ice cold people ever in this hilarious video!
