There is no question that medicine has progressed dramatically over the last century, but this does not mean that all our medical problems have been solved. Indeed, my belief is that the average life span in the Western world may actually fall in the 21st century. This is in contrast to the situation in developing countries where I expect health provision to improve and longevity to increase.
The main reason why overall health may become worse in the industrialised nations of the West relates to modern lifestyles there. This is partly because we now take less exercise than ever than before and our diet is much less healthy and there is already evidence that this has led to an obesity epidemic in many countries. Many experts are predicting that this is going to have a serious impact on their health in old age. So, for example, a child of today who grows up a diet on convenience food, rich in sugar and full of additives, and who does take regular exercise may only live to be 65, whereas current life expectancy is around 80.
The situation in the developing world is, however, quite different and overall health is likely to improve. This is because there are currently serious problems with access to healthcare and the quality of healthcare in these countries. For instance, in some places there is no local hospital or the local hospital lacks the appropriate treatment for preventable diseases such as cholera. That is likely to change in the future as the overall economy and infrastructure improves in these countries.
My conclusion is therefore a mixed one. While it is true that people may face greater problems with their health in the future, this only applies to industrialised nations and not to the developing world where life expectancy may increase.
