WOULD YOU WANT TO LIVE TO 100?
 	Remarkably, two in five girls born today will live for a century, and boys are close behind. But, asks Jeremy Laurance, is longevity all it's cracked up to be? 
 	Human beings have struggled to defeat the ageing process for millennia. From olive leaves in ancient Egypt to the alchemists' 'elixir of life', vast resources have been spent - and still are today - on tonics, potions and vitamins in the attempt to stave off the ravages of the years. Now we know the secret. Quietly, without fanfare, we are putting it to work. Life expectancy soared by 30 years in richer nations during the 20th century and shows no sign of slowing. In some countries it has increased by three months a year for the last 160 years. When the British tradition of sending a telegram from the monarch to all new centenarians began in 1917, King George V dispatched 24 celebratory messages. By 1952, the number had increased 10-fold and by 2011 it had increased almost 40-fold to nearly 10000.
 	Leading economist Professor John Appleby cites the figures in the British Medical Journal and asks: 'Where will it all end?' That is an economist's question, but one that 18th century author Jonathan Swift also wanted to answer. Gulliver's Travelsfeatures a race of humans, the Struldbrugs, who were normal in all respects except one. Their immortality, instead of being a blessing, was a curse, because they continued to age. 'At 90, they lose their teeth and hair; they have at that age no distinction of taste, but eat and drink whatever they can get, without relish or appetite... the question therefore was not, whether a man would choose to be always in the prime of youth, attended with prosperity and health; but how he would pass a perpetual life under all the usual disadvantages which old age brings along with it.'
 	In a recent article, centenarian Walter James wrote a poignant account of the deprivations of age. Though he still cooks and looks after himself, does the crossword, enjoys a glass of whisky and can recall events from his past with clarity, what he cannot recover are the sensations that accompanied the events. Recounting his sporting successes and close relationships, he notes the absence of the exhilaration that went with them. 'Perhaps the greatest loss is what it is like to be in love. I can remember the routines, the shared meals, concerts and theatres, walks in the country. But writing all this is like taking a book down from the shelf and leafing through its pages.'
 	Such observations are bound to make those younger wonder - is ageing, at the rate those of us fortunate enough to live comfortable lives are achieving, something to be celebrated or feared? The pace of advance is astonishing. As recently as 1980, scientists believed that age 85 would mark a natural limit for average life expectancy. In Japan that barrier was passed for women in 2007. In the UK, average life expectancy for both sexes born today is over 90. What is the secret - the elixir of life? Just better standards of living, education and healthcare is all, rather than a blend of exotic ingredients secretly distilled in a laboratory. Dull, perhaps, but marvellously true. In the early part of the last century, improvements in infant and child survival contributed most to growing life expectancy, but since the 1950s the biggest gains have been in the over-80s.
 	What worries most people about ageing is losing their faculties and the ability to perform the daily tasks of living - eating, dressing, bathing and getting around. The trends in this regard are worrying. The good news is that despite increases in chronic conditions such as diabetes and arthritis, earlier diagnosis and improved treatments have rendered these conditions less disabling. In the future, more of us will fall ill, but the illnesses should affect us less. The result is that we may live to see our great grandchildren and even our great-great-grandchildren.
 	Nevertheless, there are large differences between countries in healthy life expectancy beyond 65 - that is, years spent without disability - and the UK performs poorly compared with countries such as Italy and Belgium. 
 	If ageing is to be celebrated we need answers to the personal, social, financial and health challenges it poses. One suggestion, proposed by Professor Kaare Christensen, of the Danish Ageing Research Centre, is to extend working lives by shortening the working week.'The 20th century was a century of redistribution of income,' Professor Christensen says. 'The 21st century could be a century of redistribution of work. Redistribution would spread work more evenly across populations and over the ages of life. Preliminary evidence suggests that shortened working weeks over extended working lives might further contribute to increases in life expectancy and health.' Work till you are 100? Now that would deserve a celebratory telegram. How many people would welcome this opportunity is quite another matter.

INTERPOL
 	The fight against crime takes many forms. From conscientious residents who look out for each other in Neighbourhood Watch schemes to international organisations that are dedicated to bringing criminals to justice. The International Criminal Police Organisation, better known as Interpol, is one such international agency. Headquartered in Lyon, France, it operates all day, year round and was established in order for police around the globe to work together to make the world a safer place. Its emblem, which is made up of a globe, olive branches, a sword and scales, relects this. Respectively, the symbols represent worldwide activity, peace, police action and justice.
 	Interpol has four main functions. First, it provides a worldwide police communications service, which allows police from Interpol's 190 member countries to provide and share information. The second main function is to maintain and update this information in databases that police authorities can access and use. The third function is to provide support in emergency situations or with crimes that Interpol believes are priorities such as the exploitation of children. Finally, the fourth main function is to help member countries improve their police by, for example, training police agencies to deal with more recently emerging crimes like bioterrorism or cyber crime.
 	Contrary to what some people believe, Interpol is not a law enforcement agency, which means it does not actually send its officers into countries to arrest people. It is a multinational organisation that collects data on crimes and criminals and provides this information to its member countries. National police use the information supplied by Interpol in their investigations, and it is up to the country in which the criminal is in to make the arrest.
 	Interpol will often go after criminals that are involved in weapons smuggling, terrorism, drug trafficking, fraud, art theft and other crimes that involve movement across borders. Many criminals who are involved with international crime syndicates have committed crimes in other countries, and this is where the Interpol database becomes an extremely valuable tool. It is huge and contains information about unsolved crimes, criminal proiles, stolen goods and much more.
 	The database of stolen works of art is a good example of the tools Interpol has created to tackle crime. The database combines descriptions and pictures of over 38,000 missing items. When police agencies need to check if a work they have come across is stolen, the database is a quick and efficient means for them to see if the work is among the missing objects that have been registered with Interpol. When the theft of a work of art is reported, national police can have the item added to Interpol's database, which can help in recovering it.
 	In addition, Interpol produces a poster twice a year, in June and December, to publicise the Most Wanted Works of Art, much like the 'Wanted' posters for the most dangerous criminals. These posters - as well as a file of stolen works - are available at Interpol's online site. Having such a resource readily at hand enables not only police, but museums, art galleries, auction houses and prospective buyers to see if an item they are interested in buying is legitimate or stolen.
 	Interpol works closely with other organisations. In order to prevent stolen items from being sold or illegally exported, the International Council of Museums (ICOM) produces 'The Red Lists'. Each one is specific to a country or an area that is at risk of having cultural items stolen. The places represented on the lists are usually poorer or war-torn countries that do not have the financial means to protect their sites or museums from art thieves and looters. Through Interpol, the Red Lists are transmitted to police and customs oficials around the world to help them recognise objects that may have been stolen and removed illegally from their country of origin. The Red List for Afghanistan, for example, has pictures and descriptions of the general types of items most likely to be stolen and then sold in the west.
 	In Afghanistan, as in many other countries, it is against the law to sell or export items of cultural importance. With the assistance of Interpol, a number of these stolen items have been recovered. By helping police agencies around the world to do their job effectively, Interpol ensures that as many criminals as possible are arrested.
