Next week on 2 Lives... Jenn Killeen became a flight nurse on emergency helicopters because she’s good in a crisis.  JENN KILLEEN: Notoriously I perform very well under pressure. The more pressure I'm under, the better I perform. LAUREL: Is that why you do it? JENN KILLEEN: Yeah. I love it. I love it. Um, I love the adrenaline stress. It's not the adrenaline of the aircraft. It's the adrenaline of, ‘I think I just saved somebody. We just saved somebody.’ We helped somebody on their worst day, uh, in their biggest emergency on their worst nightmare. We helped. But what happens when it's their worst nightmare kind of a day. That’s next week on 2 Lives.
