The Science of Aging
The biology of aging is a complex process that involves multiple factors on the cellular and molecular levels.
One of the key processes in aging is the gradual deterioration of cells and tissues. This is caused by a number of factors, including:
Oxidative stress occurs when there are too many reactive oxygen species (ROS) in the body, which can damage cells and tissues. Telomeres are the protective caps on the ends of chromosomes, and their shortening is associated with aging and age-related diseases.
Another important factor in aging is the cellular response to stress. As we age, our cells become less able to repair damage and respond to stress, which can lead to further cellular damage and dysfunction. This can lead to a wide range of age-related diseases, including cancer, neurodegenerative diseases, and cardiovascular disease.
Overall, the biology of aging is a complex and multifaceted process that involves multiple factors on the cellular and molecular levels.
