Hiker Aron Ralston says in order to free himself, he had to twist his arm so hard that it broke. The climber spoke to reporters for the first time since being pinned under a boulder in a Utah canyon and having to cut off his arm in order to escape. Ralston says he prayed, had visions and felt a "greater presence" that gave him the strength and inspiration to break free. He said he felt a surge of energy on the third day, which happened to be the National Day of Prayer. The 27-year-old finally twisted his arm until it broke, spent about an hour cutting it off with a dull pocketknife and then hiked until he was spotted and rescued. Ralston says he's thankful for the thousands, if not (m) millions, of prayers he's received. And he's eager to get back to hiking.
