I am also one of those people who become icy calm in emergencies, but then fall apart afterwards (once it is safe to do so) as a couple serious life-threatening experiences over the years have shown me. I seemed to get back to normal pretty quickly, but my 25-year old co-worker who was in the same room with me was terrified and he really didn't appear to be back to himself until the next day and that went for many in that room. Of course, sometimes we think we are back to ourselves and aren't. I do get quite anxious for more usual stressors/situations - and it seems to take a very high level of stress to cause me to flip reaction modes. Probably something to do with survival. Very thankful that things worked out as they did and I'm sure the Denver Embassy Suites will change how they let people know when they have other practices/events like that one.
