Key Concepts

Aging

Aging is the progressive accumulation of physiological changes that occur over time, impacting the function of cells, tissues, and organs. This process often leads to a decrease in the body’s ability to repair damage, making individuals more susceptible to diseases and ultimately increasing the likelihood of death.

Cellular Senescence

Cellular senescence is the process by which individual cells permanently stop dividing and enter a state of growth arrest. This mechanism contributes to the aging process by reducing tissue regeneration and function, which can lead to the deterioration of overall health and increase the risk of death.

Mortality Risk

Mortality risk refers to the probability of death and tends to escalate with age. As individuals grow older, the cumulative effects of biological wear and tear, reduced organ function, and increased vulnerability to health conditions all work together to raise the statistical likelihood of dying.

Life Expectancy

Life expectancy is a statistical measure that estimates the average number of years a person is expected to live based on current mortality trends. It encapsulates the relationship between aging and dying, showing how improvements in healthcare, nutrition, and living conditions can influence overall survival rates and alter the typical age patterns of death.
