I just got my new chief. (old one died of old age). He is 11 years old. Since I had already done the lecture for the day with the old chief I decided to try again with the new chief, since he wouldn't be under the 24 hour limit. And he lectured the WHOLE tribe. Not just the kids. It was really neat seeing the whole tribe in the lecture hall. Not sure if the adults got any points but all the kids did.
