Now we are getting to the crux of the matter.
Its not peer pressure, its self-induced.
Why would anyone try harder for a newborn/teenager/adult/old person?
When I was doing EMS my responsibility lay with myself and the crew in that order. If the weather was good enough I would go, if it wasn't I wouldn't.
My mantra is: It is better for 1/2/3 people not to survive the accident than for 4/5/6 to die in the helicopter crash.
