This is going to sound pretty hilarious! I found this article that talks about how scientists can tell date of birth by looking into eyes. But of course not the exact date, but apparently what year the victim was born. The method they are talking about in the article can be applied in helping to identify victims of natural disasters or tracking terrorists. Interestingly, it’s also been mentioned that it could be used in “tracking down the source of tumours in the body or even studying how organs are regenerated. “ (Highfield, R. 2008). This sounds very convincing!

“Now, by measuring the amount of the carbon isotope C-14 trapped in the eye lens, scientists at the Universities of Copenhagen and Aarhus report in the journal PloS One that they can now establish, with relatively high precision, when a person was born, a useful tool for forensic scientists with which to date an unidentified body. (…)By comparing the yearly record of the content of the C-14 in the atmosphere with the content of C-14 in the lens crystallines of the eye, scientists can accurately date a person's year of birth - providing they are born after 1950.” (Highfield, R. 2008)

Sounds good to me!
