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.

New ageing clocks include ribosomal clock and immune age.
