Why can't our Sick Sims go to the hospital?

I think that they should expand on sickness, death, the cemetery, the funeral, a will, and just going to the hospital period. Unless we are visiting someone in jail, I don't really care about visiting the detective and science careers. Visiting in jail and more sickness/visiting the hospital to maybe give flowers ect. would be nice. Maybe holding sims hands when they are in bed or interaction to say, "I'm thinking about you". Also, notes for work/school when sick.

I also like other ideas from poster above such as:
chicken soup
vaccinations
over night stays
ultra sounds
plastic surgery
compensation for wrong diagnosis
