I'd like to take the opportunity at this juncture to thank all those who have contributed to a lively and thought-provoking debate. Especially those members who posed critical questions, I really had to think on my feet for a while there. Although it was a lot like walking through a cowshed at milking time, at least you haven't learned how to lick snot out of your own nostrils, or someone else's. p.s. just kidding; I bet you have learned how.
