I think its a combination of things for Harry decline in health. Dealing with the cancer and the chemo is bad enough. Add to that the first chemo damage d his heart so that has severely reduced pump capacity. Also it doesn't seem that the revised chemo was reducing the cancer. Finally an insurance company whos only concern is to make a profit over somebodys life. I got news for you Harry isn't quitting he has been worn down on all fronts. I'm still hoping and praying for a miracle so that Harry can still be around.
