Aron Ralston was a pretty normal guy, but he always had an extremely adventurous desire to travel and see the world. During his childhood, his family moved to Denver, Colorado, a place offering many opportunities to climb mountains, explore, and eventually become the adventurer he’d always wanted to be. Back in 2003, Ralston was climbing in the remote, mountainous area of Southwestern Utah, when the unthinkable happened: Aron got stuck in a crevice (裂缝) in the rocks and pinned by a big stone that weighed over 360 kilograms. The weight of the rock crushed his arm, and he was pinned by it. Aron took photos of his bad situation (which was going to get a lot worse), hoping rescue teams (救援队) would know where he was and came to remove the rock so that he could get out and home safe.

But rescuers never came. Aron waited for them for days till he lost his hope. He knew he had to do something. He was 18 meters above the floor of the valley where he was pinned in, and he had a pocketknife. He made what must have been one of the most difficult decisions of his life: to cut his own arm in order to survive. Aron cut the lower part of his arm off, having to wrench (扭动) his forearm against the big stone to break the bones, and then got himself down to the bottom of the valley, where he would begin to walk and search for help. Luckily, help arrived in the form of a helicopter (直升机) that spotted him, covered in blood. Aron had tied off the wound to keep himself from bleeding to death pretty successfully and would eventually make it out alive.

Ralston went on to become an inspiring speaker and continued to travel and climb mountains—he didn’t let an incident that forced him to cut his own arm off, stop him from doing what he really loved.
