Detecting Age From Blood Drop

Using a blood drop up to 1.5 years old, forensic experts can now estimate a person’s age to within 9 years. The thymus, the organ that pumps out T cells, is gradually replaced with fat tissue as people age leaving behind genetic artefacts.

Blood can be used to determine gender and eye color but age is tougher, bones or teeth serving as better choice ... for now.
