Don't worry about the bolded, there is no evidence to back that up. After all, the average age of Nobel prize winners in pretty much every category is mid to late 50s. Sure politics play some role there, but I doubt there are many 30-year-olds coming anywhere close to schooling those guys.
Playing devil's advocate,
* absence of evidence is not evidence of absence, and
* IIRC, there's usually about a decade (or more) between the Nobel-winning act and actually being awarded (that's still mid to late 40's if you're right, though)
But thanks for the encouragement, it's valuable to me.
