Ageing of population The problems related to the health system are particularly significant in relation to the ageing of the population, especially of Europe. According to the Eurostat, the median age of the European population is going to increase from 42.2 to 46.4 years old in 2080 and the share of the elderly is projected to increase from 18.5% (93.9 million) in 2014 to 28.7 % (149.1 million) by 2080. For this reason, Governments have to plan efficient social security systems for the future. However, the debate is heated. To build up a welfare state able to cure freely everyone, is nearly impossible. Consequently, several experts propose to invest in prevention campaigns, highlighting the huge number of pros. Effective campaigns prevent diseases from spreading in the future and characterize the ultimate expression of the right to health. Nevertheless, some people argue that should be better to spend more money on providing cheap and quality medical treatments to who is actually ill. I believe that, implementing widespread preventing campaigns and policies that aim to promote healthy lifestyles, in particular among children and teenagers, is possible to reduce the future number of ills. At the same time, the hospitals and doctors can concentrate better on who is sick or has the greatest risks to be. For example, in my opinion, free sporting initiatives dedicated to kids and elderly have a great social importance: encourage aggregation and the maintenance of a healthily lifestyle. Despite this, an additional problem has to be considered: without policies aimed to reduce pollution, contamination and other environmental hazards, it is impossible to hope to reduce healthcare costs and the number of ills.
