Strange aberration

We tend to think of the habit of piercing various parts of the body and inserting ornaments as something to be associated with the quasi-religious customs of primitive tribes in remote regions of the world. Yet we have plenty of it in our own so-called civilised societies, even if we make an exception for that minor piercing of the ear-lobes which is considered necessary for the safe attachment of jewels intended to enhance the countenance.

In a review published in The Lancet for 5 April, by Aglaja Stirn of Frankfurt am Main, some of the medical consequences and the psychological motivations of body piercing are examined, in the wake of increasing popularity of body piercing throughout the world. It is practised by individuals of many different social and age groups, despite the discomfort involved and the risk of inflammation and infection.

As Dr Stirn points out, piercing of ears, mouth and nose has been common practice in almost every society as far back in history as can be traced. It is especially common in Africa, Asia and South America. Apart from considerations of beauty and community spirit, motivations include ritual initiation, rites of passage and sexual enhancement. Religious traditions play a great part in determining its incidence, which may indicate devotion to a certain deity or a wish to transcend the normal limitations of bodily existence.

Body piercing may be regulated and confined to accredited practitioners, or unregulated and carried out in department stores, jewellers' shops, homes or physicians' offices, generally without recourse to antibiotics and under variable criteria of sterilisation of implements. As regards site of puncture, ear lobes and ear cartilage are commonest, but eyebrows, nose, cheeks, lips, mouth mucosa, tongue, uvula, nipple, navel and genital areas are also used. Complications occur — commonly bleeding. The inserted material should be surgical steel, niobium, titanium or gold (14 or 18 carat); brass and nickel should be avoided they are likely to induce skin reactions.

Many factors influence the incidence of acute complications. Local infection may occur in 10 to 30 per cent of cases, navel, ear and nose being the commonest sites. Redness, swelling, warmth, pain and drainage of pus are typical.

As regards motivation for the process, several psychological and sociological factors may be involved, particularly in teenagers. It may be a desire to make a personal statement, to show daring or to be fashionable. Peer pressure is often given as a motive, the wish to fit oneself into a group that one admires. It strikes me, however, that to bow to peer pressure indicates a degree of self-surrender and a lack of personal power and integrity. It shows not a measure of strength, but of weakness and inability to stand on one's own two feet and assert one's personality. So why do people, teenagers in particular, feel it necessary to fall into line rather than assert superiority?

Plastic problem

Bisphenol A is a phenolic compound used as an intermediate in the manufacture of epoxy, polycarbonate, phenoxy and polysulphone plastics. Although it is insoluble in water it dissolves in alcohol and dilute alkalis. This may present a problem of toxicity in certain applications, as has been reported in Science for 4 April.

In studies of meiosis carried out in a laboratory in Cleveland, Ohio, mice were found to be suffering from oestrogen disruption after their cages, constructed of polycarbonate plastic, had mistakenly been washed with a highly alkaline detergent. This treatment led to the leaching of bisphenol A from the cages, which caused abnormal chromosome development.

Plastics containing bisphenol A are used in the manufacture of a wide range of products, including infants' feeding bottles, liners for food cans and seals for dentures. The finding that it is liable to be leached out in the process of deterioration through ageing, or contact with an alkaline solution, sounds a warning that should be taken seriously.

Seeking the truth

In Nature for 17 April, Robert Hedges, a research archaeologist at Oxford, comments on a snag in dating artefacts without taking account of human behaviour as well as physical data. Today we have many methods of applying scientific techniques to determine how old an excavated object may be, including radiocarbon dating, but we neglect to take into account human conduct that may have influenced its history. Hedges remarks that it is not always satisfactory to rely on the present to explain the past, or on the other hand to interpret behavioural evidence in purely rational terms.

For example, radiocarbon dating tells us what time has elapsed since the death of an organism, that is, when it ceased to be metabolically connected with atmospheric radioactive carbon. But carved ivory derived from an Anglo-Saxon site excavated by an archaeologist may have been fashioned from a much more ancient mammoth bone, so that the date scientifically determined differs much from the date in terms of human activity. Large fragments of wood in which annual rings can be counted allow the calibration of radiocarbon dating but are not helpful in determining the date when an artefact was constructed from them.

When an object is older than 50,000 years little radiocarbon is left in it and supplementary investigations become necessary. The dating of Neanderthal flints in a cave in Israel by thermoluminescence has been assisted by electron spin resonance determinations in animal teeth found in the same strata. And controversy over the age of volcanic tuff in Kenya, estimated as 1.9 million years, has been resolved by comparing results of potassium-argon and fission-track techniques. Ancient bones record the isotopic composition of the individual's diet, and the contribution of marine food and animal versus plant protein, but for accurate estimates we need to use data from living populations in the region also. In human settlements on the Danube, there is evidence that aquatic food was important, and radiocarbon dating of spear points embedded in the skeletons shows that the dates for the humans are several centuries older than those for the spearheads. The discrepancy is resolved if the humans consumed much fish and the animals providing the spear points grazed on terrestrial sources of carbon.

Ancient wisdom

A man assumes that wealth is the greatest good. This falsehood contains venom, it feeds upon his soul, distracts him, does not allow him to sleep, fills him with stinging desires, pushes him over precipices, chokes him, and takes from him his freedom of speech.
— Plutarch: 'Moralia' (c.AD100).
