A Wired post explores the difference between chronological and biological age. It takes a look at several studies that try to correlate age with various biomarkers, though finding true age is hard because people age at different rates. Says the post, "While dozens of biomarkers are correlated with age ... none of them is a good enough match to provide full-proof age determination. The same holds true for even the most advanced genomic expression studies."
