Living Will
  
Walking across the street one day, you get hit by an ice cream truck. Now you're in a coma. Your kids are fighting about what to do. Madison wants to pull the plug. Eddie also wants to pull the plug, but wants to wait a little bit...he's hoping to find a copy of your will first, just to make sure he's got an inheritance coming.
Meanwhile, you have no say...because you're just lying there, drooling into a pillow.
You should have set up a living will. It describes how you want these kinds of situations handled. It provides a list of your wishes for medical care and other related topics if you end up unable to communicate...like from a freak ice cream truck accident.
