I've played two games now. In each, one of my original villagers liked to run. Wow, what a useful tool. Now in my second game, one of the runner's children likes running, too. Does anyone know if it's possible to breed for runners, or is it simply random? They get things done fast and level up quickly.

And on that note, has anyone detected any significance at all to any other villager likes and dislikes (bananas, coconuts, butterflies, flies, the dark, etc.)?
