Coming home with a catheter isn't unusual either, you need to practice scrupulous hygiene with it but that becomes a habit too. Its very unusual these days for it to be permanent, just need to get him sorted.
Know what you mean about white hair, mine seemed to appear over night. Am home early today, the forest was full of men and cars and vans, all with their lights on, filling the carpark where I go and strung out up the roads away into the distance....not sure what it was...film crew, lost person, night sports thing of some kind...bloody nuisance as i has to come back home without walking the boys. They have just had breakfast and are currently ridding the garden of monsters so they aren't too bothered luckily.
