Consider a schematic version of this, based on those Norwegian soldiers learning to parachute: the first time they jumped, their blood pressure was through the roof at the time of the jump (Part B). But in addition it was up for hours before with anticipatory terror (Part A), and for hours after—still weak-kneed (Part C). By the zillionth time they jumped, what was the profile like? The same massive stress-response during the jump (Part B), but two seconds before and after, nothing—the parachuters are just thinking about what they’re going to have for lunch.
