Here are some skill and status related questions from me...
If a villager has mastered in one particular skill, should I keep him/her at it or should take him/her to master in someting else instead? And if I leave a Master Scientist doing research, will that accumulate more points than if I switch to just an adept or trainee scientist?
Is there a maximum age for breeding, and is it the same for men and women?
What does "elderly" status mean/do? If a villager is in that status, is there any way to help him?
