The original poster wished to determine _chronological_ age.

In: 

Testing the Theories of Aging - Chapter 2 - Longevity is Determined by 
Specific Genes : Testing the Hypothesis : 
Section VII. BIOMARKERS OF AGING AND LONGEVITY

Richard Cutler (citing Bada, 1980) implies that determining the degree
of racemisation will give a reliable indication of chronological age.

Perhaps someone can comment on this with authority. :-)
