NHS advice to wanna-be fathers

I was looking through the NHS website the other day, and came across this sound advice for any man who wants to become a father...

"make the decision to quit the fags today if you want to make a baby."

I think something was lost in the translation...for those of you who don't know, a "fag" is what the English call a cigarette! Sure sounds funny to an American!
