I have a female who, as soon as she turned 14, I started at farmer. As soon as she had the basket of berries I left her as I had a few other things going on at the time. I kept checking on her every once in a while and she was doing what she was supposed to be doing so I left her alone. When she was 18 I went back to her figuring she might like a change in occupations and she is still only a trainee farmer. I couldn't imigane what was wrong with her so I decided to watch her to see what the problem was. Every time she got to the food hut to drop off her food, instead of going off to work, she was shown as eating and I would see the message "you're villager feels better after eating". The really wierd thing is her name is "HUNGA". I have since switched her to research and she is now 21, and at the upper end of adept.
