Very meta! :-)(Though not 100, strictly speaking)
103 (not including the repeated 'words')....and a number.
Ahhh. Cunning. I wouldn't have picked it as so close, however ... but I will take your word for it as I see your obsessiveness may be more extreme than mine!
aaaand you were correct. A more accurate count (may as well earn the obsessiveness title) is 156 words including 'words' twice PLUS two numbers (2013 and 67%). Shame on me.
