If my 9&#x2F;11 experience is a guide, then you will have months of overreacting to everything...from the sick feeling in your gut when you see a clear blue sky with no contrails in it like I did that fateful Tuesday, to the moment of doubt when you take your mail out of the mailbox after the Anthrax attack.<p>It goes away and you realize that the equilibrium in a civil society is normalcy, and to give in to fear is to lose.  Recency bias, forgetting your math&#x2F;probability&#x2F;statistics--you&#x27;re smarter than that.  Lead the way for others to keep calm and carry on.
