Understanding Aging at a Cellular Level
Aging is a complex process that occurs at the cellular level, involving damage to DNA, the accumulation of senescent cells, and the aging of the immune system. These factors contribute to age-related diseases such as cancer, dementia, and heart disease, which are significant causes of mortality globally. The relationship between aging and disease risk illustrates that aging is the greatest health challenge humanity faces, as it underlies many conditions that increase with age. Addressing the fundamental biological processes of aging could lead to improved health outcomes and longevity.
