There was a documentary entitled 'Death' on TV last night.

I don't know which puzzles me more: the number of TV documentaries about death, dying, and terminal disease, or my propensity to watch them. You would think that with continual news reports about fatalities in Iraq, Afghanistan, Palestine and Darfur (oh, and Congo, Lebanon, Burma, etc) that the TV companies might lighten the mood occasionally with more nice stories about fox cubs tumbling around in the woods and computer graphics-enhanced explanations of the water cycle. You would also think that when I stop worrying, dutifully, about global warming, terrorism, obesity, world population and the new clamour for a renaissance of nuclear power - and forget about my parents' eating and cleaning habits - I'd be ready to reread 'Wind in the Willows' or reorganise my beer label collection. But that's not the way it is, apparently. It seems like we've all developed a taste for the morbid these days.

It could be that the aging baby boom is finally beginning to acknowledge its mortality. This is a dreary thought. It means that for the next twenty or so years we are going to be deluged with morosity and hypochondria.

On the other hand, it could be entirely subjective. Perhaps it is all just me viewing the world through black-rimmed spectacles.

The interesting thing is how absolutely free of morbid thoughts are mum and dad. Well, mum seems pretty thought-free all the time, so it is hardly surprising that I can cite something she doesn't think about. And dad has had a peculiar attitude all his life. He was positive - he never let himself get too bothered about bad things - but not particularly ambitious. He would often express exasperation at the doings of the world. Watching a news report about a serial killer, for example, he would say 'I can't understand these blokes' - but he never seemed to see the world as something that he could improve. Thinking about it now I realise that he was not motivated by the need to transform things. While he wanted to do good deeds, he was fatalistic deep down - so there was simultaneously little effort to right the big wrongs and little ambition to climb high. He has consequently little fear of death - it is simply one of those untransformable things, an immutable fate. I must remember to ask him about it next time I am there. Mum too, for that matter.

The one benefit that lies hidden beneath the costs of Alzheimer's is that its victims are often unaware of their problem. The agnosia is commensurate with the decline: the worse they get the less they know about it. So, given that both mum and dad can get up in the morning and walk, fiddle around in the kitchen until something edible presents itself, and live in a climate that is (for now) stupendously benign all adds up to a picture that death barely figures in. Simple - the basics for survival are all still there. There really is no need for them to think about anything other than their daily preoccupations (running out of cash in dad's case, and how to get rid of the bearded intruder in mum's).

So, yes, it seems maybe it is just me, and come to think of it, this weekend I did see a documentary that featured fox cubs.
