My son tells me that volcanic ash attracts its own lightning. We both think that this would be a great effect in a Hollywood movie. I am up well before the winter's dawn, again with my persistent toothache. It seems that something is always going wrong with my aging body. Doctors and dentists can usually take care of these ills and thank goodness for provincial health insurance, but it takes time to see the doctors and I must live with some discomfort until I am cured. It was not like this when I was younger, but, on the whole, I prefer the advantages having lived a long and very full life, although not a particularly useful one perhaps. I know this is "begging the question", but it is largely true. I live for myself and my own pleasure. We used to argue that Mother Teresa and Florence Nightingale did too, but now I see the error of the argument, however young people should not be particularly exhorted to live a "useful life". Much better they should be encouraged to find a way to be happy and to promulgate "the greatest happiness of the greatest number".
