I've just been watching an esteemed elder cooling his feet in the stream whilst carrying a bowl of water. I decided to see what would happen next. He then chose research (I uncheck their preference boxes as soon as they become elders, so they do what they like). He carried the bowl to the research table and hung onto it while conducting research. Then he went into the research hut and when he came out it had turned into a bowl of berries. So funny LOL
