In another one of my interesting linguistics lectures (no more 'eats shoots and leaves' for now :p : ) I found that women don't actually talk as much as men! From a corpus of language, it is found that (from the British National Corpus):
Females speak a total of 3,267,444 words
Males speak a total of 4,920,742 words
I find it hard to believe, women always seem to have the most pointless conversations
