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?
