Article 12: Right to physical and mental health 34. With a view to the realization of the right of elderly persons to the enjoyment of a satisfactory standard of physical and mental health, in accordance with article 12, paragraph 1, of the Covenant, States parties should take account of the content of recommendations 1 to 17 of the Vienna International Plan of Action on Ageing, which focus entirely on providing guidelines on health policy to preserve the health of the elderly and take a comprehensive view, ranging from prevention and rehabilitation to the care of the terminally ill. 35. Clearly, the growing number of chronic, degenerative diseases and the high hospitalization costs they involve cannot be dealt with only by curative treatment. In this regard, States parties should bear in mind that maintaining health into old age requires investments during the entire life span, basically through the adoption of healthy lifestyles (food, exercise, elimination of tobacco and alcohol, etc.). Prevention, through regular checks suited to the needs of the elderly, plays a decisive role, as does rehabilitation, by maintaining the functional capacities of elderly persons, with a resulting decrease in the cost of investments in health care and social services. Articles 13 to 15: Right to education and culture 36. Article 13, paragraph 1, of the Covenant recognizes the right of everyone to education. In the case of the elderly, this right must be approached from two different and complementary points of view: (a) the right of elderly persons to benefit from educational programmes; and (b) making the know-how and experience of elderly persons available to younger generations. 37. With regard to the former, States parties should take account of: (a) the recommendations in principle 16 of the United Nations Principles for Older Persons to the effect that older persons should have access to suitable education programmes and training and should, therefore, on the basis of their preparation, abilities and motivation, be given access to the various levels of education through the adoption of appropriate measures regarding literacy training, life-long education, access to university, etc.; and (b) recommendation 47 of the Vienna International Plan of Action on Ageing, which, in accordance with the concept of life-long education promulgated by the United Nations Educational, Scientific and Cultural Organization (UNESCO), recommends informal, community-based and recreation-oriented programmes for the elderly in order to develop their sense of self-reliance and the community’s sense of responsibility. Such programmes should enjoy the support of national Governments and international organizations. 38. With regard to the use of the know-how and experience of older persons, as referred to in the part of the recommendations of the Vienna International Plan of Action on Ageing dealing with education (paras. 74-76), attention is drawn to the important role that elderly and old persons still play in most societies as the transmitters of information, knowledge, traditions and spiritual values and to the fact that this important tradition should not be lost. Consequently, the Committee attaches particular importance to the message contained in recommendation 44 of the Plan:
