Aging is a complex biological process characterized by the gradual decline in cellular and physiological functions, leading to increased vulnerability to diseases and ultimately death. It is influenced by genetic, environmental, and lifestyle factors, and is a major focus of scientific research aiming to extend healthspan and lifespan.

Aging

A biological process is a series of events or molecular functions that occur in living organisms to sustain life, such as metabolism, cell division, or photosynthesis. These processes are essential for growth, development, reproduction, and maintaining homeostasis in an organism.

biological process

Cells are like tiny factories inside our bodies that do all the important work to keep us alive and healthy. They have special jobs like making energy, building things, and sending messages to other cells.

Cellular Functions

Physiological functions refer to the processes and activities performed by living organisms to maintain life, encompassing everything from cellular metabolism to the operation of entire organ systems. These functions are regulated by complex biological mechanisms that ensure homeostasis, adaptation, and survival in varying environmental conditions.

Scientific research is like a big treasure hunt where scientists try to find answers to questions about the world. They use special tools and follow steps to make sure their findings are true and helpful.

Healthspan refers to the period of an individual's life during which they are generally healthy and free from serious or chronic illness. It emphasizes not just the length of life, but the quality and functionality of life, aiming to extend the years lived in good health rather than merely prolonging life expectancy.

healthspan

Lifespan refers to the maximum duration an organism is expected to live under optimal conditions, influenced by genetic, environmental, and lifestyle factors. Understanding lifespan involves studying the biological processes of aging and the impact of external variables on longevity.

Genetic factors refer to the inherited traits and variations in DNA sequences that influence an individual's physical and physiological characteristics, as well as susceptibility to certain diseases. Understanding these factors is crucial for advancing personalized medicine, predicting disease risk, and developing targeted therapies.

Genetic Factors

Environmental factors encompass all external elements influencing living organisms, including physical, chemical, biological, and social components. These factors shape ecosystems and human health, driving adaptation and evolution, and are critical in assessing ecological and public health risks.

Environmental Factors

Lifestyle factors encompass the daily habits and behaviors that significantly impact an individual's overall health and well-being. These factors include diet, physical activity, sleep, stress management, and substance use, all of which can influence the risk of developing chronic diseases and affect longevity.
