Bubble Thickness

Peter Gordon nudged me to take Charles Murray's 20 question quiz to reveal my type.   I answered "yes" to two of the 20 questions.  Please email me which ones you think I checked "yes".  I'm not sure that I achieved any greater self awareness but I did enjoy taking the quiz.

As I tell my students on exam days, "Exam Days" were always my favorite days of the year and now I don't get to take them anymore.  The funny thing is that I have the feeling my students believe me.
