1. Understanding Average Life Expectancy and Age 84
Life expectancy refers to the average number of years a group of people born in the same year are expected to live if mortality patterns remain constant. While it is an average, understanding this benchmark provides a basis for exploring why some individuals may not reach it, and others may exceed it. The relevance of age 84 comes from its proximity to the current average life expectancy in many developed nations.
1.1 Global Life Expectancy Trends
Global life expectancy has significantly increased over the past century due to advancements in healthcare, sanitation, and nutrition. However, there are considerable variations across countries and regions. According to the World Health Organization (WHO), the global average life expectancy at birth was around 73 years in 2019 (1). This number has been affected by various global events, like the COVID-19 pandemic, underscoring the dynamic nature of mortality trends.
1.2 Life Expectancy in Developed Countries
Developed countries often have higher life expectancies compared to the global average. For example, in countries like Japan, Switzerland, and Australia, life expectancy commonly exceeds 80 years (2). The United States, while still a developed nation, lags behind some of its peers, with a life expectancy hovering around the late 70s (3). This disparity is attributed to factors such as healthcare access, lifestyle choices, and socioeconomic conditions.
1.3 Why Age 84 Matters
Age 84 is a significant milestone because it is slightly above the average life expectancy in many Western countries. Understanding why people might die around this age involves examining the common health challenges that older adults face, as well as considering individual lifestyle and genetic predispositions. Factors contributing to longevity versus early mortality can provide insights into proactive health measures.
2. Common Causes of Death Around Age 84
Several common causes of death are more prevalent in older adults, including those around the age of 84. These often stem from chronic diseases, age-related decline, and external factors such as infections.
2.1 Cardiovascular Diseases
Cardiovascular diseases, including heart disease and stroke, are leading causes of death worldwide. As people age, the risk of developing these conditions increases due to factors like accumulated arterial plaque, decreased heart muscle strength, and increased blood pressure (4). Around age 84, many individuals may have been living with cardiovascular issues for years, and these conditions can become fatal due to complications or acute events like heart attacks and strokes.
2.2 Cancer
Cancer is another major cause of death in older adults. The risk of developing cancer increases with age due to accumulated DNA damage and decreased immune function (5). Cancers such as lung, colorectal, breast, and prostate cancer are frequently diagnosed in older adults. By age 84, the cumulative effect of cancer development and progression can lead to mortality, especially if the cancer is diagnosed late or is aggressive.
2.3 Respiratory Diseases
Respiratory diseases, such as chronic obstructive pulmonary disease (COPD) and pneumonia, also contribute significantly to mortality in older adults. COPD is often linked to smoking and long-term exposure to pollutants, while pneumonia can be particularly dangerous for those with weakened immune systems (6). At 84, the respiratory system may be more vulnerable to infections and chronic conditions, making respiratory diseases potentially fatal.
2.4 Neurodegenerative Diseases
Neurodegenerative diseases like Alzheimer’s disease and Parkinson’s disease are more common with advancing age. These conditions gradually impair cognitive and motor functions, leading to increased disability and mortality (7). Alzheimer’s disease, in particular, is a leading cause of death in older adults, as it progresses over time and leads to complications such as infections and malnutrition.
2.5 Infections and Immune System Decline
The immune system’s effectiveness declines with age, a process known as immunosenescence. This makes older adults more susceptible to infections such as influenza, pneumonia, and other infectious diseases (8). Even common infections that younger people can easily fight off can be life-threatening for someone aged 84 due to a weakened immune response.

3. Factors Influencing Mortality at Age 84
Several factors contribute to the likelihood of death around the age of 84. These include genetics, lifestyle choices, socioeconomic status, and access to healthcare.
3.1 Genetic Predisposition
Genetics play a significant role in determining lifespan and susceptibility to certain diseases. Some individuals may inherit genes that predispose them to conditions like heart disease, cancer, or Alzheimer’s disease (9). Conversely, others may inherit genes that promote longevity and protect against age-related diseases. Understanding one’s genetic predispositions can help inform preventive healthcare strategies.
3.2 Lifestyle Choices
Lifestyle choices, such as diet, exercise, smoking, and alcohol consumption, have a profound impact on health and longevity. A healthy diet rich in fruits, vegetables, and whole grains can reduce the risk of chronic diseases, while regular exercise can improve cardiovascular health and overall fitness (10). Avoiding smoking and limiting alcohol consumption can also significantly reduce the risk of premature death. The cumulative effect of these choices over a lifetime can influence whether someone reaches or surpasses the age of 84.
3.3 Socioeconomic Status
Socioeconomic status affects access to healthcare, nutrition, and safe living conditions. Individuals with higher socioeconomic status typically have better access to quality healthcare, healthier food options, and safer environments, which can contribute to longer lifespans (11). Conversely, those with lower socioeconomic status may face barriers to accessing these resources, increasing their risk of disease and premature death.
3.4 Access to Healthcare
Access to timely and quality healthcare is crucial for preventing and managing age-related diseases. Regular check-ups, screenings, and vaccinations can help detect health problems early and allow for prompt treatment (12). Individuals who have consistent access to healthcare are more likely to manage chronic conditions effectively and receive necessary interventions to prolong their lives.
4. The Impact of COVID-19 on Mortality in Older Adults
The COVID-19 pandemic has had a disproportionate impact on older adults, significantly increasing mortality rates in this age group. The virus poses a greater risk to those with underlying health conditions and weakened immune systems, which are common among individuals aged 84 and older.
4.1 COVID-19 as a Leading Cause of Death
In 2020, COVID-19 became a leading cause of death in the United States, particularly among older adults. The Centers for Disease Control and Prevention (CDC) reported that 81% of COVID-19 deaths in 2020 occurred among those aged 65 and over (13. In this age group, COVID-19 was the third leading cause of death, after heart disease and cancer.
4.2 Increased Death Rates by Age and Sex
The CDC data revealed that COVID-19 death rates increased with age among adults aged 65 and over. The death rate for those aged 85 and over was significantly higher than the rate for those aged 75–84 and 65–74. Furthermore, men experienced higher COVID-19 death rates compared to women in all age groups (13.
4.3 Disparities by Race and Ethnicity
COVID-19 mortality rates also varied significantly by race and ethnicity. Among adults aged 65 and over, Hispanic and non-Hispanic Black individuals experienced the highest COVID-19 death rates, followed by non-Hispanic American Indian or Alaska Native (AIAN) individuals (13. These disparities reflect systemic inequities in healthcare access and socioeconomic conditions.
4.4 Place of Death
The CDC data also highlighted differences in the place of death for COVID-19 patients aged 65 and over. Most COVID-19 deaths in this age group occurred in healthcare settings, but a significant percentage also occurred in nursing homes or long-term care facilities. The percentage of deaths in nursing homes increased with age, with a higher proportion of deaths among those aged 85 and over occurring in these facilities (13.
5. Strategies to Increase Longevity and Healthspan
