How can one claim that packing suitcases is intrinsically more stressful than checking administrative documents, as if this hierarchy was carved in stone for every traveler and destination? The maximum stress doesn't lie in the task itself, but in the ultimate consequences of its failure. If the passport is expired for a trip outside the Schengen area, the entire project collapses, making the stress of packing absolutely trivial. It is the asymmetry of risks that dictates the level of stress, and a missing document can wipe out all efforts of perfect preparation.
