Are there other ways to prove someone's age?

Question

FIRST OF ALL THIS QUESTION HAS NOTHING TO DO WITH ME:

Let's say you are 17, haven't reached puberty so you took a bone age test(performed by doctors) that said the bone age is 11. It hasn't changed now that you are 23.

Is there any other way to prove you really ARE 23?

Answer 1

Any kind of examination is only going to show findings consistent with a certain age--it can't tell you the age exactly.  You could show that the end plates of the bones have fused, for example, and that would show that the person probably wasn't under the age of puberty.  But that doesn't prove anything about what the age actually is, since people reach puberty at different ages, and if there's a problem, it would be misleading.  The same would be true of other things like physical development, eruption of molars, whatever.  A bone age of 11 in a 23-year-old would be quite worrisome, so if this is any real person, I hope they're getting good care.

People are not trees; you can't just count rings.  ;-)  They'd have to carry a driver's license or other form of ID.

birth certificate?
