None of these "assets" that are supposedly lost after 30 are a function of age. Yes, there is likely a correlation.
However, even if there is a trend to be observed, the information is only useful to someone trying to select from a group of candidates, and then only if the selector is unable to distinguish between candidates on the basis of the desired characteristics. The trend is of no use to the candidates.
Thinking that you have an advantage simply because you are young is foolhardy. Lamenting that you are at a disadvantage because you are over 30 most likely reveals your lack of fortitude. You either are (and intelligent curious dedicated &rest important-attributes) or you are not.
