Understanding Aging and Biological Age

The video explores the science of aging, distinguishing between chronological and biological age. It highlights that aging begins at the molecular level and manifests in physical changes and diseases. Biological age, unlike chronological age, can be influenced by lifestyle choices. The video discusses methods to measure biological age, such as phenotypic age, and emphasizes the importance of lifestyle in slowing aging and reducing disease risk.

What is the common misconception about aging?

• Aging is not influenced by lifestyle.

• Aging is solely determined by chronological age.

• Aging is a sudden process.

• Aging starts only after birth.
