As a medical provider, I would tell Walter and his family that lifetime and life expectancy are not the same thing. Lifespan is the longest a person may live in perfect biological conditions, which is usually around 000 years. Life expectancy, on the other hand, is the average number of years a person is projected to live based on statistics for a group of people (Lally & Valentine-French, 0000, p. ___). Life expectancy is affected by real-world factors and can be very different from person to person, while longevity has a biological maximum limit. Walter is only 00 years old when he is diagnosed, which is significantly below the average lifespan for people. However, his life expectancy is lower because he has terminal lung cancer. This helps explain why his experience is different from what his family would have thought it would be.

Our life expectancy is impacted by a great number of significant elements. Several factors, including a family history of cancer, as well as lifestyle decisions, play a crucial role in the development of cancer. Environmental exposures, such as air pollution and occupational dangers, as well as levels of stress, as well as nutrition, exercise, and socioeconomic status that hampers access to healthcare, also have a significant influence in the development of the condition. Gender and age both have an effect on risk trends throughout time. There are a number of reasons that could have contributed to Walter's cancer diagnosis, including a possible smoking history or environmental exposure. These factors had an effect on his life expectancy, despite the fact that there had been great advancements in therapy.

According to the theory that was created by Elisabeth Kubler-Ross, there are five major emotional stages that humans may experience when confronted with the prospect of death. These stages include denial, anger, bargaining, depression, and acceptance (Lally & Valentine-French, 0000, page 0). It is possible for individuals to shift back and forth between these stages or experience many stages at the same time because these stages are not sequential. According to Walter's circumstances, he can first exhibit denial by withholding his diagnosis from his family. This could be because he is having difficulty accepting the fact that he is afflicted with sickness. It is possible that he will experience anger as the diagnosis becomes more real to him. He may wonder why this is happening to him, or he may feel frustrated about the financial load of therapy.

Because Walter is hoping to either lengthen his life or enhance the outcomes, his decision to pursue therapy may be a reflection of his desire to bargain. Over the course of time, he may suffer depression, which is defined by feelings of sadness, withdrawal, or fear. This is because he is confronting the progression of his illness and the influence it has on his identity and relationships. There is a possibility that Walter will eventually arrive at acceptance, which means that he will come to terms with his condition and concentrate on spending quality time with his family. These stages may also be experienced by members of his family, often at different periods or in different ways, which can have an impact on the way they connect with one another and the emotional dynamics that they experience. When Walter and his family have a better understanding of these stages, they will be better able to normalize their emotional responses and seek the proper emotional and psychological support during this challenging time.
