Your age isn't on your website, but my calculation (got Master's degree in 1986 at likely approximate age of 24) couldn't have been TOO far off, right?
Well, it was farther off two years ago when I posted the picture. And I got my MA in 1986 on my 22nd birthday. (Later got an MLIS on another birthday.) I put a math problem in my follow-up post. You should be able to calculate my age and my son's ages from these clues: http://sonderbooks.com/blog/?p=10000
My age estimate was from your LinkedIn profile. If I was guessing by pictures, I would have said 39. (Is that the right answer? (I mean in the sense of Right Answer to say to someone of how old they are, not mathematically correct. :-) ))
The Right Answer is to have not brought up the age issue because it is rather immaterial to the discussion. Can you really say that the authors age, when considered independently from the article subject, has significant bearing on the voting?
I guess age is just one of those topics..... :-)
