Question

Some suggest that the gains in life expectancy observed in the past 100 years reflect successful interventions in aging. Is this correct? Discuss why or why not.

Short answer

While successful interventions in aging such as advancements in medicine have contributed to increased life expectancy over the past century, other significant factors including improved sanitation, better nutrition, and safer workplaces have also played major roles. Therefore, attributing the rise in life expectancy solely to interventions in aging might oversimplify the complexities of this trend.

Step-by-step solution

Define the claim

Clarify what is meant by 'successful interventions in aging'. This could include medical or pharmaceutical developments, changes in public health policies, or societal factors that support better health and longevity.

Review life expectancy trends and their causes

Analyze the factors that have been conventionally linked to increased life expectancy over the past 100 years. This can include factors like improved sanitation, the advent of vaccines and antibiotics, better nutrition, and safer workplaces and living conditions.

Weigh the evidence

Now, evaluate to what extent these factors can be considered as 'interventions in aging'. If these factors typically affect health outcomes before old age (for example, infant mortality), they could be considered as interventions in the aging process

Formulate your argument

Based on the evidence, form an argument either in favor or against the statement. Include caveats or alternative interpretations, if any.
