Yeah I know, I was just being flip, sorry

I have read things to the extent of what you've posted before, but I do not believe it causes a very noticable difference (if at all) and it doesn't hurt them. If it did I certainly wouldn't do it. I don't do it all the time, just every once and a while. I do like the nice neat, clean appearance it gives though.
