My mother died last year and he was her sole caretaker due to a disability caused by a ruptured brain aneurysm 25 years ago. My dad was already in bad health, but she kept him motivated to stay active. Over the last year, he has slowly been starving himself and has become determined to die. He weighs less than 90 pounds and was a six foot tall man. I imagine that his body, at this point, could not recover even if he changed his mind. I realize that he misses mom, but, we all do. I try to read to him but he says no, I try to engage him in conversation but he won't. He tells me to be quiet.
