    As a first responder, you never know what type of situation you might walk into, or who you’ll meet along the way. That’s definitely been the case for Jeffrey Lanenberg, a 51-year-old paramedic(急救医务人员) since 1984.

Ten years into the job, Lanenberg received a call that reported that a man in his early 30s had fallen down in the Mall of America. When Lanenberg and his partner arrived at the scene, they found the young male face down on the ground. He had gone unconscious, making weak attempts to breathe. His wife stood beside him holding their small son in horror. They quickly rushed to defibrillate(除颤) and calm the man to keep him under control. After Lanenberg dropped the patient off at the neighboring hospital, he thought about the man and his family for a long time.

Lanenberg thought he had experienced everything under the sun until one random visit to Office Max three years ago, where he met a man repeatedly walk back and forth while staring at him. As it turned out, the man was the patient he had saved 20 years earlier.

＂You gave me 20 years more than I ever thought I’d have,＂ the man said. He thanked Lanenberg repeatedly and told him he had someone he wanted him to meet. He stepped around the corner and reappeared with a 20-something-year-old man. Lanenberg instantly knew that it was the son he had seen standing by his mother all those years ago.

＂That day changed my life,＂ Lanenberg said. ＂Before that, everything was about work…When I talk to my beginner-training class, I tell them you never know the impact you can have on someone’s life.＂
