Everything about Jake is average: he's not particularly tall, not particularly strong and, as a man in his late 30s, he's getting a bit heavier with every day he spends mostly behind his desk.

One of the most characteristic elements of Jack, in the days of healthy livestyle and vaping, is the smell of cigarettes that follows him. It seems to have impregnated his worn brown suit and his shirts are grey rather than white (despite his best attempts to bleach them, they seem to absorb the smoke all the time).
