eyeshigh has to be correct. I had one guy that had no likes or dislikes when I started my last village and I put him to work as a builder. He easily became a master builder (course, there is stuff to work on at the beginning) without me ever having to pick him up and plop him back on the building like most of them. Then I started him farming and I had to constantly drag him away from "fixing the huts" back to farming. Eventually he mastered that. He fathered a daughter whom I put to work building as soon as she was old enough. Everytime I checked on him, he was trying to help his daughter. Next, I put him at the research table and he again was constantly trying to help his daughter or "fixing a hut". He did become an Esteemed Elder, but not until he was 62.
