We are honoured to be hosting this world event in Spain. Our interest stems from our realization thatthe ageing of the population presents a challenge for which we must prepare ourselves and that we must beready to take advantage of the abilities of older persons. Therefore, in offering to be the host country, Spainwished to demonstrate its interest in policies for the integration of older persons and to give impetus to aninnovative debate in our society.

We are living through a period of major demographic change. The elderly are ever more numerous.That people are living longer and under better conditions, as a result of social progress, is one of humanity'sgreatest achievements. Older persons are a universal force with the potential to transform. the future. Thisglobal transformation is going to affect individuals, families, communities and virtually every area of society.[TONE]∥[TONE]
Accordingly, we must prepare ourselves for this new challenge by promoting changes in attitude towardsthis demographic revolution, which is taking place because of the increase in the number of older personsin the world. Achieving a society for all ages involves analysing society from a broader perspective andhighlights the role played by relations between the various generations making up society. Solidarity betweenthe generations in all areas of family, community and national life is essential for social cohesion. [TONE]∥[TONE]
We younger people must be increasingly aware that, in order to move forward in building a more just society, we must recognize the advances made by older generations and value their experience and currentabilities appropriately. At the same time, we must be able to transmit such values to coming generations.Inter-generational solidarity is a natural setting within which encounter, learning and exchange take placeamong individuals. It offers advantages to all and helps in achieving a more integrated society. [TONE]∥[TONE]
Together we will build a positive image of ageing, which should involve not simply prolonging life, but also ensuring that old age is healthy, independent, active and fully integrated in society. Ageing should be seen as astage in life during which men and women can still develop their skills, as active agents in our societies, in whichthey should continue to participate as full citizens with full social recognition. [TONE]∥[TONE]
I hope that all the proposals that result from this World Assembly will enable our society to face the challenges posed by the ageing of the population, and that they will be translated into practice by the greatestpossible number of countries in such a way that older persons will benefit from them as soon as possible.
Thank you. [TONE]∥[TONE]
