If the tragic story dominating the news is provoking your thinking about end of life issues, you may want to look at the web site of the Family Caregiver Alliance. It has lots of helpful information on end-of-life decision-making, feeding tubes, legal issues, advance directives, and letting go. It also has tips on caring for indviduals incapacitated by various illness, advice for long distance care-givers, and directories of support resources for care-givers. This site is packed with useful information none of us want, but all of us need.
