Show Time Remaining in Hospital in the Status side bar where it says In Hospital.  This way a player is more away of how much time is remaining. 

I.e.  Status: In Hospital (03:44)

Perhaps status timer could be added to the friends/enemies list as well?

Also if you're on someone's profile it could say the reason for jail or hospital like attacked by ARMPIT.

I like this, or at least show it on the hospital page at the top or something.
