    On January 15, 2009, the crew of US Airways Flight 1549 experienced a never-in-a-lifetime event. Less than two minutes after takeoff, some birds found their way into the airplane’s two engines and brought them to a sudden stop. Over the next three and a half minutes, the crew managed to identify the problem, decide what to do about it, and make the most successful emergency landing in aviation (航空) history.

We all experience similar moments. Running into the person you canceled a date with – while you’re on another date. Realizing you hit “reply all” on an e-mail that you’d do anything to have back. Earthquakes, medical emergencies – whatever the situation, the first thing you probably do is panic. Everybody does. While many of us think that we’re cool in a crisis, science tells us that we seldom are. At the moment we need to be keenly aware of our surroundings, but our attention goes to the scariest thing on the scene, leaving us unaware of the other sights, sounds, and even smells around us. At the moment, we’re anything but at our best.

These normal human reactions can be reversed. For example, firefighters are taught how to bring down their blood pressure and heart rates quickly, Box breathing, belly breathing, hum breathing – you can learn these techniques in minutes. Once you calm down, you’ll identify accurately what the problem is really about. Lack of practice always causes us to judge problems in wrong ways. Doing the thinking ahead of time also helps you fire off the solution when it’s show time. This is why you are advised to find the closest exit before the flight. And sometimes we aren’t prepared with all the knowledge we need. Let’s say we’re on a hike and a bear shows up. What shall we do? Better to read suggestions on how to respond before heading into the wild.

Performing in a crisis is becoming more important for all of us for two reasons. Back in the good old days, the reliability of most anything we used or did was far less than it is today. Now think about what happens to our preparedness as the likelihood of something had happening reduces. Unless we practice what hardly ever happens, our ability to respond when it does happen tends to slip away. Reliability can kill you. Also, the systems we use today are more complex. There are seldom moving parts in plain view that allow us to see when things are about to go wrong. Consequently, terrible situations can “come out of nowhere”. Ironically, the systems that were designed to lessen our workload might require us to remain in a state of increased vigilance (警觉) in order to survive these increasingly infrequent events when they do happen.

As technology becomes part of most everything, and as once-large risks break into countless small ones, crisis situations may become standard affairs. We should all learn to breathe, recognize the situation, and carry out the plan that we are smart enough to prepare well in advance.
