"But we'd get back down, and when we were safe we'd say, Man was that great!" he recalled. "You forget how scary it was, and you go back again."
Psychologists note that some people seem to have a strong craving for adrenaline rushes as a thrill-seeking behavior or personality trait.
Like many extreme athletes, Emily Cook's appetite for risk appeared at a young age.
"I was both a skier and a gymnast," said the former U.S. aerials ski champion. "I was one of those kids who enjoyed and excelled at anything acrobatic, anything where you were upside down. It was just kind of a part of Emily."
When Risk Becomes Real
Cook noted that as her expertise grew, so did the stakes. In a sport where skiers perform acrobatic tricks from the height of a five-story building, the consequences of a mistake can be serious.
"As I started doing harder tricks, I was drawn to the fear factor," she said. "There are definitely moments when you're up there doing a new trick and it seems like the stupidest thing in the world. But overcoming that [fear] is just the coolest feeling in the world. Doing something that you know most people wouldn't do is part of it."
Cook was forced to give up her spot on the 2002 U.S. Olympic ski team when risk became realityshe broke both feet during a training jump shortly before the games.
After two and a half years of surgeries and recovery, Cook recently made her first practice jumps into the splash pool at the training facility in Utah Olympic Park. She has set her sights on competing the 2006 Winter Olympics in Torino, Italy.
How did the injury Cook experienced change her outlook on risk?
"As an inured athlete coming back, generally my reaction is to stop and reduce the risk a bit," she said. "I've had to change my mentality a little bit now."
"I'm moving up to a jump that was natural before the injury, but now there is a fear of pain, injury, and even the fear of not being able to do it like I could before," she said. "Your body does remember how to do these things. But your mind sometimes gets in the way a bit."
Shane Murphy, a sports psychologist and professor at Western Connecticut State University, has worked with Olympians and other athletes. He says he is struck by the way they redefine risk according to their skills, experience, and environment.
"I've worked with groups climbing Everest, including one group without oxygen. To me that just seems like the height of risk. But [the climbers] took every precaution they could think of," he said. "To them it was the next step in an activity that they've done for years. They weren't going out there to get hurt."
Murphy said the perspective of extreme athletes is very different from our own. "We look at a risky situation and know that if we were in [that situation] we would be out of control," he said. "But from the [athletes'] perspective, they have a lot of control, and there are a lot of things that they do to minimize risk."
As Read, of Exum Mountain Guides, is quick to note, climbing and other "dangerous" activities are statistically not as risky as outsiders would assume.
Another key aspect of risk perception may be something referred to as "the flow" or "the zone." It is a state in which many athletes describe becoming absorbed in pursuits that focus the mind completely on the present.
"Something that makes you begin climbing, perhaps, is that your adrenaline flows and you become very concentrated on what you're doing," Read said. "After it's over there's exhilaration. You wouldn't have that same feeling if the risk hadn't been there."
People of different skill levels experience "flow" at different times. As a result, some may always be driven to adventures that others consider extreme.
"I can enjoy hitting the tennis ball around, because that's my skill level," Murphy said. "But others might need the challenge of Olympic competition."
