According to Jung one can develop functions. And according to MBTI and Socionics you can have a mental capacity above/at/under your physical age.

* X represents til the end, not physical death but spiritual death
*** hypothesis 1: collective consciousness, type and death are related - more on that later maybe. ***
*** hypothesis 2: age 6-20 are the golden years for now after reading a most likely self explanatory reason ***
*** hypothesis 3: psychosis is the prolonged (what is it 6 months for schizophrenia diagnosis?) or delayed awareness of tertiary(3rd) and inferior(4th) psychological function (Jung model) ***
Why types correlate:
http://en.wikipedia.org/wiki/Socionics content 4
http://www.socionics.com/articles/howto.htm
Which means that functions correlate, how that works:
Mental/Vital functions, Accepting/Producing functions, Inert/Contact, Valued/Unvalued or subdued functions, Evaluatory/Situational functions, Bold/Cautious functions, Conscious/Subconscious functions and Weak/Strong functions.
