A small drop of 'preservative' in the water will do you no harm. In fact it may well be beneficial as it kills bugs in the water too.
I have been told that it keeps elephants away as well.

That would be a problem with bungalows but I sleep upstairs. It will be a matter of "I told you so" and the bungalow dwellers will rue it when not sleeping upstairs encourages the big cats to return to prey on man. I am not quite so worried about elephants as the stairs would probably not support one.

What am I saying? Your prudential suggestion is, on second thoughts, necessary. I keep the port under the stairs.

"Upstairs" is a purely temporary concept to an elephant.

Varley,
A person of your standing should never have to undergo the taking of water of dubious freshness. A tincture made with something from the Hebrides would do the trick.

#1 for update.

Regret Hebridean tincture is the one of two doubts I have about my Duncan/Lang blood (the other being porridge) tincture of tincture (Drambuie), however is a pleasure. Not one, however, to be used as disinfectant.

Perhaps I should just put a pint of Bushy's beside the bed every night. But then how would I sleep until I had emptied it (not to mention increased frequency of gettings up to pee)?

#1 for update.

#1 for update. Very disappointing. Last week lost the best part of 5 Lbs. This all back again. I did have two pints on Friday and a barbeque that involved a small amount of cheese over and above a normal meal otherwise I have been a model of temperance. Double sod it.

#1 for update. All disappointing still. Hovering at or a miniscule amount below 19 St.

Knees remain relatively easy after Naproxen but I know if I take to walking again they will be back to impossible in no time.

#1 for update. Fractionally better this week. See knee consultant tomorrow. Benefits from Naproxen still not worn off yet.

Well, saw the bone setter this evening. I am allowed a new knee, six months from date of order.

Should I do it. Intelligence welcomed.

Do it if it will make you feel better and not have pain daily.

Mother-in-law had one replaced years ago. She said it was a huge success, and was pain-free. According to her the procedure was a doddle (not how I would describe someone cutting out and throwing away a bit of your anatomy) and wouldn't have minded getting the other one done.

Unfortunately she had many other problems, but the knee was fine.

David I have had both knee joints replaced,(not at the same time) not a problem anymore.
Just make sure you buy an extention seat for your throne as sitting on it is painfull the first week.
