In your everyday activities, are you running, crouching, pressing yourself against the side of a building, maybe lying down? Are you routinely flinging yourself out of the line of fire? It's 80°F in Israel today, they've been running and fighting, probably had to look at the map once or twice and yet there's no sign of sweaty fingers that have handled the documents? I'm sure they stopped in the middle of their infiltration, too, to wash their hands.
