Alan, I think you are wasting your time. I think there are loads of people reading this thread who are going to return from their week/fortnight in Egypt, most put out because they haven't been bitten once! There will be the odd few who have been brutally "lipped" and maybe in the odd case "nipped" by some Red Sea fauna, who will, probably unintentionally, start the whole "man eating Red Sea fish" saga off again!
