In previous game sick Sims were actually sick I think you'll hear them cough, sneeze and throw up and they will be out from work and school and sleep and eat grandma healthy soup, Sims 4 it just feels unrealistic like sick Sims taking medicine and it's miraculously healed I would like the option for sick Sims going to the hospital get diagnosed and get cured there or if the doctors feel you need some from school or work write a doctor's note for a day or two and that Sims take medicine and rest up even lingering symptoms like throwing up, coughing, sneezing, running to the restroom, stomach cramps, pack aches. Still have the other Illness but enhance it you know like some have polka dots or striped body why not have creams to sooth them feeling hot headed use ice pack.
