Longevity

Biological Age Measurement (Clocks):

• Epigenetic clocks: Good at predicting age, but unclear direct correlation with randomness and cellular functional damage.

• Telomere length: Damage is more important than length itself, limiting its value as a single indicator.

• Transcriptome/proteomics-based clocks: Promising in terms of mechanistic understanding and correlation, but still in early research stages.
