It would only take me a couple of hours but I don't know why I would be there. He is losing weight like crazy but does have saliva on his tongue so he is not dehydrated yet. I don't know how much weight is safe. We have been married over 50 years (I was 10) just kidding..and I have never seen him this thin. He is 5'9 and now weighs 170 that was a week ago so probably less now. I think they would think I am totally crazy for bringing him in because we know why he is losing the weight.
