Chronological age isn't necessarily the same as cellular age. A middle-aged person may have a biological age of plus or minus 15 years.
- biological age is a better indicator of future health
- dozens of different aging markers study - including glycan, telomere length and methylation patterns
- different parts of body can age at different rates
- brains of older people who exercise regularly look 10 years younger
- looking older could be a sign of an underlying disease
Identify where and how you are aging so you can target your anti-aging strategy and employ the most appropriate rejuvenation treatments.

Protein Patterns of Ill HealthThe Scientist - 02-Aug-2018
Certain sets of proteins are associated with common conditions of aging. Blood samples taken from over five thousand of elderly Icelanders. Measured 4,137 known and predicted serum proteins within the samples. Found 27 distinct networks, or modules, of proteins across the cohort. Many of the networks were associated with specific complex diseases. Also revealed patterns of expression associated with overall mortality.
Size Of Nucleolus Might Predict LifespanInverse - 21-May-2018
Nucleolus is in the center of the cell's nucleus. It is where the cell’s protein-making machines — the ribosomes — are made. Size of the nucleolus can determine the rate that a cell ages. Organisms with smaller nucleoli tend to live longer. NCL-1 — a gene linked to nucleolus regulation — may play a role. Accelerated aging diseases have bigger nucleoli and more ribosomes. Can’t say for sure yet whether the link is cause-and-effect.
Using AI to Predict Biological AgeGenetic Engineering & Biotechnology News (GEN) - 30-Mar-2018
Physical activity data from wearables can produce digital biomarkers of aging. AI-based algorithm created by GERO outperformed previously available models. Produced a separate deep CNN for mortality risks prediction. Life and health insurance programs already provide discounts based on physical activity.
