If you have ever been annoyed or rude with a telemarketer, there is a true story you should hear:
In May 2002, Leonardo Diaz, a Colombian hiker, decided to do some serious mountain climbing with friends. Their goal was to reach the summit of the Nevado del Ruiz, a volcano in the Andes.
On the second day of the climb, a major blizzard hit. Diaz lost sight of his friends and became separated from them. Although not initially worried, the novice climber soon began to run out of rations and suffer from the bitter cold. Although he had his cell phone in his backpack, his pre-paid minutes had already expired. With no way to signal for help, Diaz realized he was not going to make it.
