The next time I head for the airport security line, ready to be scolded for wearing too large a wristwatch, I will have to make a quick decision. The Transportation Security Administration (TSA) now asks passengers to sort themselves into three different lanes on the basis of their experience and efficiency as travelers (and packers).
In my case, one of the lines rules itself out at once: this is the line in which families with children unload sufficient objects to carry them 40 years in the wilderness. I’m past that. But the next choice is not so easy: shall I get into the “Black Diamond” line for expert travelers, or am I a casual traveler, indicating perhaps inexperience or the worry that my toothpaste tube may be .0003 of an ounce too large to allow me to dash through the lane?
