My comment about the SAs having no noticeable body odor came out the notion that persons on a dangerous mission emit an easily identifiable smell, a smell not unlike that emitted by an unwary target when suddently confronted with danger. Innocents need not worry about these unintentional fear emanations. Same for an old time warrior whose body has evolved to emit a persistent stench of constant fear that overrides transitory wafts of panic aerating an urge to flee or submit. Constant fear of being attacked comes from daily warfare in NYC, call it urban terrorism, where territorial dispute is unending, and there is nobody who is not out to grab what you got, most often under pretense of helping you, offering friendly advice, getting inside your defenses with the kind of behavior you are sure you'd never fall for -- upon later reflection on what happened to yor best laid plans to not be suckered. Over-confidence, in attacker and target, that lack of the odor of danger, is certain to draw attention to weaknesses ready for exploitation. This bunker is saturated with moth balls, still visitors complain of rotted carcass. BO plenty.
