I never said a 15 year old COULDN'T know as much as a 45 year old. But I DID say a 45 year old who has owned herps all their life MOST DEFINITLY has more experience than a 15 year old simply because of time. You cannot argue that. They can have potientially 30 more years experience than a 15 year old could possibly have no matter how many reptiles that 15 year old has. Period.
Not to say I reject teenagers advice as many are as knowledgable as an adult. It all depends on the individual.
