Re: Something JA (bless her) did not understand about sex...

I am sorry for all the men that you think are impotent, although I doubt that there are "many" in their forties. The environmental factors would not have applied to Mr Knightley and his contemporaries. Mr Knightley was active (he walked), not an alcoholic, and not eating over-processed food etc. He did not smoke and certainly would not be abused by Emma!
