Nowadays, we live in an ageing society, and we can observe how several countries have an increase in their older population. There are many reasons why people are living longer, but I will highlight three main factors: scientific progress, access to health services, and lifestyle choices. Firstly, the number of studies related to health diseases has increased over the years. For example, the study of neurodegenerative diseases, one of the most critical fields in Europe, has risen significantly, especially in Western Europe, the region with the greatest number of older adults. These researchers are concerned about how people can keep their cognitive processes into old age. Secondly, there has been an increase in health services in all countries. Several medical institutions and hospitals have been established with many different specialists. It is not only private institutions that provide highly specialized treatments, but also governments have created excellent public services. Besides, services to prevent diseases are working, i.e., gyms, nutrition services, the development of children consultancies, psychological counselling, etc. Finally, the third reason; people today are more willing to learn how to take care of themselves. We can see on social media a lot of information related to choosing a better lifestyle. New generations prefer regular exercise, healthy food, and a better environment. Additionally, big companies promote health because they think it is better for the performance of their employees. So to wrap up, life expectancy around the globe is increasing as people become more conscious about their health and there are more health services for everyone.
I hope that my changes have helped. I have used the present perfect tense to explain things that happened in the past without a defined time, and they continue up into the present. If you require any further clarification, please do not hesitate to ask š
