Although the concept of health care power of attorney is not as elegant a process as it could be, I believe that it is sufficient. If I were to enter into a coma for a prolonged period of time with little to no chance of awakening from it, I believe next of kin should have the right to decide if it would be kinder to let me go.

It is ridiculous, as these groups and people serve vital roles in society. It's time to stop fighting and just accept it.
