Let's say you are at the airport and you wish to spot a terrorist. You see, spotting a terrorist is not easy but from novels and the little military knowledge I have, I know that you can spot one by the person yawning frequently and excessively, he/she displays incessant arrogance due to the fact he is in a haste not to be caught, then the body smell of the individual is a very bad one as they have no time to clean up or stuffs like that. For the males, their faces are often pale as a result of beards shaving, they check their watches from time to time and lots more. Now, if you notice this whether you are sure or not, do well to tell the responsible authority to clarify and probably save lives.
