Climbing beyond your fears
Imagine looking up and seeing a high wall of rock going hundreds of meters into the air.

While rock climbing really is a dangerous sport, most people use ropes to protect (them). The ropes will catch you if you fall. But others, like 31-year-old US climber Alex Honnold, make rock climbing crazier.
Honnold made a great (achieve) this month when he climbed one of the world's most famous cliffs (悬崖). E1 Capitan in California, US, is 914 meters high. Honnold climbed it ropes or even a helmet (头盔). If he slipped (踩滑) and fell, he would have died.
Not everyone that does rock climbing is as crazy as Honnold. Many do it safely, even on special indoor (wall). It is a great way to build strength and exercise your body. According to The Huffington Post, working out the best way to climb up a wall also (develop) your problem solving skills.
