I think they should add cleanliness to the game. Actions and days of our heathling should leave a wound debuff that leaves no damage and can increases over time. Giving random debuffs.
You would need to wash yourself in the lake to reduce the stench, and use soups to give your hearthling a buff that keeps cleanliness longer.
Animals are attracted to overly clean and underclean hearthling more.
having a nasty hearthling reduces the % bonus of feast and table reductions.
this way people like snail have to shower for once in their life, even if it's ingame.
