Not sure about any of it. I am out of the loop on anything health related, he says it is none of my concern. I know he is still hacking up alot and has been for the past few years, I told him that sounds horrible maybe you should get it looked at...i'm good is all he says. I was finally able to sit down and watch concussion today and it so happens H came by just as we started it. He watched it and was very intrigued by it...but said nothing. Tomorrow we go to the VA..am praying that he can get help...but it is up to him whether he takes it...after this i consider myself done ...i have done all i can do..honestly having the eggshells feelings on friday showed me that I am done..I like peace and tranquility...i do not want the negativity
