Many pharmaceutical companies, which are among the world's largest, invest millions in research into heart disease and conditions which typically relate to the process of ageing. These areas, where research costs are phenomenally high, also offer the greatest potential. Research on curative drugs may be less expensive but the rewards are less because the patients, who will get better, will not need the treatment for years and years. On the other hand, conditions like Alzheimer's disease, heart disease or arthritis, which last for years, could involve long periods of treatment. It is these areas, therefore, which offer the best potential for high profits. A further point is that such research is intended to produce drugs which will be marketed into the richest countries where profit will be highest.
