While we don’t have a definitive answer to the exact limit of human lifespan, research suggests that several factors contribute to the current bottleneck, or the point at which lifespan seems to plateau.
One major factor is aging itself. As we get older, our cells and tissues naturally deteriorate, making us more vulnerable to diseases and illnesses. This process of aging is influenced by various factors, including genetics, lifestyle, and environmental factors.
Another important factor is the accumulation of cellular damage. Our cells are constantly exposed to harmful agents like radiation, toxins, and metabolic byproducts. This damage can accumulate over time, leading to cellular dysfunction and eventual cell death. While our bodies have mechanisms to repair this damage, they become less efficient with age.
Beyond the cellular level, genetic factors play a crucial role in determining lifespan. Some genes are associated with longevity, while others contribute to premature aging. The study of these genes helps scientists understand the complex mechanisms of aging and identify potential targets for interventions.
Research suggests that the current “limit” of human lifespan is around 122 years, but this is not a fixed value. As we continue to learn more about the aging process, new interventions might emerge to push the limits of human lifespan.
