Pied Piper
Well they took a bloody big chunk off me a couple of years back for very similar reasons and here I am telling the tale.   I cant tell you not to worry because you will. I can say dont drink whisky or anything similar, not at all good in that situation. But the odd pint of wallop in the Peveril shouldn't do any harm (I have my spies). And bagpipe music is pretty much bound to stimulate the immune system, I would have thought.
