The nurse found Mr Beckenbaum, like a rat, with the cheese in his mouth.
The neighbours talked, the press reported. The details differed, though the
diagnosis did not. The title: Cholesterol Clot. When the choice was between
diet and destruction, Mr Beckenbaum had turned his back on the one, and salvation
with it, only to be caught in the end by a vulgar piece of mousetrap.

Counting the costs of a cleaner world
Recycling waste is not always the best way ahead either for the environment or for the economy, reports Roy Ecott* in Zurich
Recycling, an activity once restricted to the conscientious minority, has become "flavour of the decade". During the past ten years the number of towns and cities in the US with recycling schemes has swelled from 140 to more than 2,700.
But a few bold thinkers at universities on both sides of the Atlantic now suggest that recycling may not benefit the environment as much as many believe, and is certainly not as economically viable as it might seem.
As a viable economic activity recycling is a complicated business. On the whole, people are aware of how rubbish is collected and sorted, but they forget about the marketing of the end product. Yet that is often the key question.
As Dr Eric Johnson of Mobil Plastics Europe said: "There is a world of difference between recycling industrial waste and post-consumer waste - in terms of cleanliness and contamination, as well as cost."
Although people are generally aware of what kinds of waste are re-usable, they do not always know the full story. For example, it is effective to melt down glass and aluminium to be used again, but with glass a great deal of energy is used in the process.
With aluminium there is an energy saving of 95 per cent compared with that used in making new metal. But the manufacturers say that "even if the many billions of aluminium cans produced in Europe each year were to be collected, that would still be just the tip of the iceberg".
Also, householders who are happy enough to save cans often forget to hand in bigger items such as frying pans and saucepans when they reach the end of their useful life.
Although certainly useful, the re-smelting of aluminium does not guarantee financial success. Refonda, Switzerland's only recycling plant for that purpose, was forced to close this year for economic reasons. The metal collected now has to be exported to Germany for reprocessing.
Paper is another popular item for recycling. But the process is not straightforward. The best-quality wood fibres can only be recycled up to six times, because the cellulose breaks down and the fibres become too short to use, or are lost in the process.
"Recycled paper is weaker than fresh virgin paper," said Erkki Peippo from the company Finnboard. "So more of it has to be used to fulfil the same functions. This means a cardboard box made from recycled pulp would have to be up to 50 per cent heavier than one made with virgin fibres if it is to be as strong."
Not only is recycled paper low in strength, it is low in hygiene too, with high proportions of heavy metals and biological organisms that require strong biocides to kill them.
Forests are not threatened by papermaking. Wood pulp for paper is farmed in the softwood forests of the northern hemisphere in a similar way to cereal crops.
An increasing number of experts are convinced that refuse-derived fuel is the best way to dispose of household rubbish. Plastics are a good example, as they are derived from petroleum, and can be incinerated as a concentrated form of petroleum energy.
"Owing to the various molecular structures of different plastics, they should ideally be recycled individually if they are to be re-used their intended applications," said Johnson, and that is a tricky and expensive business.
Some companies have tried blending plastics to make innocuous products such as road cones or park benches; but there is a limit to the number of road cones and park benches people want.
For the moment the EC still considers incineration as a useful way of disposing of refuse. Countries such as Denmark, Japan, Sweden, Switzerland and Britain have started establishing incineration plants to burn household refuse to ensure some form of energy recovery, to re-use the heat directly or to power electricity-generating turbines.
More and more governments are legislating to encourage recycling. But economic considerations are not taken sufficiently into account. Companies complain that they are not being given enough time to find out what is feasible or necessary, and what is simply a waste of time.
Even for those products that can be easily and economically collected and recycled, a market for the final product must exist before recycling becomes worthwhile, otherwise rubbish is being turned at great expense into new rubbish which ultimately has to be dumped.
In Germany the strictness of the packaging ordinance has given rise to instances of cargoes of plastics being shipped abroad, because there was no money to be made from it. German rubbish has turned up in uncontrolled landfill sites in Portugal and as far away as Sough Africa.
Professor David Pearce from the centre for social and economic research on the global environment at University College in London, an advocate of the principle that the polluter must pay, said: "Politicians are so active against packaging waste on merely opportunistic grounds. They get away with it because householders can identify with the issue. Politicians can act without appearing to impose a great cost on the electorate, whereas moves to control global warming would hit voters in a much more noticeable way.
