Hey Nick, no need to wish you good luck, although it's a major job, bypass surgery is extremely successful, a 98% success rate as a matter of fact. So by the time you read this message you should be on the road to recovery ... However I will wish you all the best with two normally incidental activities,"COUGHING and SNEEZING". Unfortunately for the next few weeks either of these two activities will introduce you to a whole new world of pain ... Cheers Glenn
