keep your guard up

A young man and several friends drove to a ski resort, went through a gate that contained warning signs about the dangerous condition of the slopes, and started snowboarding. On the second trip down the mountain, someone shouted, “Avalanche!” but the young man couldn’t escape and perished in the cascading snow. Some in the media severely criticized him for being a novice, but he was actually an “avalanche-certified backcountry guide.” An avalanche researcher said that seasoned skiers are most likely to be seduced into faulty reasoning. He said, “[The young man] died because he was lulled into letting his guard down.”
