watching people6 foot tall. Graying hair shows some white. Shaved back and sides a clue to the past; a military build. Wrinkles here and there, not bad for his age. Long black coat, utilitarian clothes. Nothing fancy. Working clothes. This is a working man.
In good condition, his steps do not falter. Grey eyes that have seen to much. Holding back; does not let you in. Pain; old pain but still there. A confident approach, calm, calculating, looking to get to the point. Straight forward. Stand up straight. Eyes focused on the job. Every move specific to the task at hand.
Ready to more. Like a snake ready to strike. Waiting to strike. Will strike when necessary. Eyes are piercing, looking constantly, trying to figure out what's going on.
