These are troubled times. We have a strike of water workers. I have been worrying for weeks whether the water would continue to run out of the taps. I even laid in a stock of Perrier water. In London at any rate, the water still runs. As to the Perrier water, almost my favourite drink, I cannot allow myself to drink it until the situation becomes acute. Then there are the interminable talks over the limitations or even reduction of nuclear weapons. The outcome of these talks is easy to surmise: they will end with all the nuclear powers possessing more nuclear weapons than they did when the talks started. Once I would have worried about this also. Now I look forward to drinking the Perrier water even if the water talks succeed.
