Q1: What is the scientific definition of 'longevity' and how does it differ from 'life expectancy'?

A1: Longevity refers to the especially long-lived individuals within a population, while life expectancy is a statistical average indicating how many years a person of a certain age can expect to live. Longevity studies often focus on the mechanisms and methods to extend maximum lifespan, whereas life expectancy is used as a population health measure. The maximum verified human lifespan is 122 years for women and 116 years for men.

Q2: What are some common myths about human longevity and how do they compare to scientific findings?

A2: Longevity myths often involve exaggerated claims of lifespans well beyond those scientifically verified, such as stories of supercentenarians and longevity practices in folklore. Scientific evidence currently supports a maximum possible human lifespan of around 127-150 years under ideal conditions, with the longest verified lifespan being 122 years.

Q3: What recent scholarly research models the mathematical limit of human longevity, and what are the key findings?

A3: Recent demographic research has introduced the 'Weon model,' a modification of the Weibull model, to describe human survival and mortality curves. This model suggests there is a mathematical limit to human longevity, with predictions indicating a maximum lifespan between 120-130 years. The complementarity principle proposed by this model posits that as average longevity increases, the mathematical maximum may decrease due to mortality dynamics.

Q4: What role do genetics, diet, and lifestyle play in influencing human longevity according to recent scientific studies?

A4: Current scientific consensus highlights that genetics, diet, and lifestyle are significant factors affecting human longevity. Genetics may determine the upper limit of lifespan, but lifestyle choices such as diet, exercise, and avoidance of harmful habits (like smoking) are critical in achieving longer, healthier lives. Research underscores that no single factor guarantees longevity, but a combination of healthy behaviors can maximize life expectancy.

Q5: How does the 'Compensation Law of Mortality' relate to disparities in longevity expectations among different socioeconomic groups?

A5: The 'Compensation Law of Mortality' suggests individuals with higher mortality rates (often correlated with lower income) experience greater longevity uncertainty but age more slowly. As a result, they may derive more utility from longevity risk pooling, such as through life annuities. This highlights growing disparities in longevity between rich and poor, with socioeconomic status significantly impacting both lifespan and the perceived value of insurance products.

Q6: What does the latest clinical research say about interventions to improve longevity and function in senior populations after injury?

A6: A recent randomized clinical trial, the STEP-HI study, evaluated combining supervised exercise with topical testosterone therapy in older women after hip fracture. The study found that a multimodal, high-intensity exercise program, with or without testosterone therapy, improved functional outcomes compared to usual care. This suggests targeted exercise interventions can enhance recovery and potentially extend healthy years in seniors after significant injuries.

Q7: What is the current record for the oldest verified human lifespan, and how does this compare to animal species known for exceptional longevity?

A7: The oldest verified human lifespan is 122 years and 164 days, achieved by Jeanne Calment. In contrast, certain animal species far exceed this: for example, Galapagos tortoises can live over 175 years, and bowhead whales can surpass 200 years. These comparisons highlight both the remarkable, yet limited, longevity of humans relative to some species in the animal kingdom.
