I'm also aware of a few other age/skill type relations.
Musical ability frequently manifests early -- by age 4-5 in numerous historical cases.
Talents requiring physical coordination -- ballet and gymnastics -- around age 9-10 by Russian tradition.
Maths and scientific curiosity perhaps early adolescence.
Complex logic and activities requiring a fully developed inhibitory function (avoiding reflex and rash actions) possibly early 20s.
I'm suspecting other forms of more synthetic (as in: assembling from parts) logic might not develop fully until the 30s or 40s. Other skills might similarly not develop until later.
