And for the poster who stated that his "wife is a doctor who works 24 hour shifts", my comment to you, and she, is "How totally IRRESPONSIBLE for a person with that amount of responsibility, to do that!".
Please post her name and the place where she works - I sure as hell wouldn't want to be one of her customers/patients!!
Hmmm I'll inform my wife about this when she arrives home in an hour after a 24 hour shift being the senior resident paediatrician in the main hospital covering a large London Borough (population 300,000). I'm sure she'll be glad to find out just how irresponsible she's been looking after all those sick children's lives.
And she has to do it all again on Sunday.
