You need to talk to someone who has been through this. Amazing ignorance. My Father died drowning in fluid... but at home like he wanted... he could not eat or drink the last week of his life. The water was pouring off of him and he had difficulty breathing. My Grandfather the same in the last two weeks before he died. How many loved ones have you had to personally up close and personal watch as they pass on?
Again.
I am not talking about the very end of life when people are in the process of dying, when nothing can help a person because they are dying.
I am not talking about the last week, days or hours of physiological shutdown.
