The main task of the mod is to prevent generation of a new NPC, forcing the game for various roles and careers (maid, postman, etc.) to use existing Sims.
This mod adds the chronic condition Asthma. Your Sim will randomly experience coughing or sneezing which will trigger an Asthma attack. When you have an attack click on your Sim to use the inhaler interaction or anti-inflammatory medicine interactions. Both will remove the ashtma attack buff and give your sim relief.
