It's hard to get people to actually put their wishes down in writing, and there are some practical limitations to it, as well. I think it's more important to make your wishes known to those around you. You'd be surprised how many families have given little, if any, thought to what their moms and dads and grandparents would want in these types of situations. IMO any person over the age of about 40 or 50 should make known to their loved ones and physician how much intervention they want if they can't communicate those instructions in a time of medical distress. Obviously it's a bit more difficult if you have no close friends or family, of if you've alienated everyone in your social and familial circles. No plan is foolproof. But the more people know your wishes, the more likely they'll be honored if you can't make them known, yourself.
