yeah i can give you examples to help you out be remember weather you civ or mafia or a detective, old man or woman or a child, you would have to think up your story to macth up who you are but think of it as this old people have different perks to a child. child can see things others cannot and find hiding places easier, down side to being a child your not going to be able to solve puzzles easy.
old people have experance and may have a few perks then normal and good with puzzles (they would get hints on the puzzle), downside weak and slow at running and fighting, so may not be able to defend themself from attack from a mafia
