Biological Age

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.

Nucleolus is a life expectancy predictor – Phys – 31-Aug-2017
The nucleolus is a major structure in a cell’s nucleus responsilbe for ribosome biogenesis.
Max Planck Institute for Biology of Ageing has discovered a link between its size and life expectancy.
Biomarker found in study of long-lived roundworm Caenorhabditis elegans mutants.
Mutants showed smaller nucleoli than their shorter-lived relatives.
Size link was independent of the pathway that led to their longevity.
Molecules within the nucleolus could causally impact life expectancy.
Effect also seen in human muscle biopsies.
