The Living Will enables you to make decisions about the care you receive at the end of life. Many people dread being hooked up to machines when there is no chance they will ever recover. The Living Will tells your healthcare providers and your agent what your wishes are, allowing you to pass with dignity as you define it.
As with the Durable Power of Attorney for your financial matters, if you recover from your incapacitation, you can once again make your own healthcare decisions. Also, you can revoke your Living Will at any time, as long as you have the legal capacity to do so. But having a Living Will and Healthcare Proxy in place now can provide peace of mind for you and avoid difficult decisions for your loved ones.
