Episode notes
Biological Age Beats Chronological Age
- Chronological age is just time elapsed and often misleads our judgments about health and function.
- Biological age reflects molecular and cellular changes that drive the later visible signs of aging.
Aging Starts At The Molecular Level
- Biological age measures how much your biology has changed and predicts dysfunction and disease risk.
- Aging begins at molecular and cellular levels and later produces functional declines like vision, balance, and hair graying.
Aging Rate Is Malleable Across Species
- Different species and individuals age at different rates, showing aging is malleable.
- Comparing survival curves reveals the species-specific pace of aging and human variability in decline.
