Teen Driving Restrictions Little Impact

Research shows that deadly car accidents aren't really about driver age but driver experience.

States with strict teenager driving laws wanted to separate novice drivers from dangerous situations. Basically since its inception in 1996, drivers of graduated programs were linked to 1,348 fewer fatal crashes involving 16-year-old drivers but 1,086 more fatal crashes involving 18-year-old drivers.

This means restrictions on driving only limits exposure to risky situations but eventually those kids will have to navigate those situations - and that's where the trouble is born.

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.
