Nothing but the name overlaps. A will distributes your property after you die. A living will, usually part of an advance directive, tells doctors what treatment you do and don't want while you're alive but can't speak, things like ventilators, feeding tubes, and resuscitation. You need both, they do completely different jobs, and having one does not give you the other.

An advance directive is the umbrella document stating your medical wishes. A health care proxy (or medical power of attorney) names the person who decides for you when you can't. A financial power of attorney names who can handle money, bills, and property while you're incapacitated. All three only operate while you're alive; at death, your will and your executor take over.

Now, and those are the two most common reasons people give for waiting. Planning is not about age or wealth: it's about the people who would have to clean up without instructions. Research by Empathy puts the average work of settling a loved one's affairs at 420 hours. Most of that is preventable with an afternoon of decisions and a few signed documents.

Your state has a plan for you, and you haven't read it. Dying without a will is called dying intestate: a court applies a fixed formula to decide who inherits, a judge chooses who raises your minor children if the other parent can't, and your family works through probate with no instructions during the worst weeks of their lives. Doing nothing is a choice too. It's just the worst one available.
