HI RUSS,
I am in the age bracket where I have been through this with friens also. I know how it hurts and my prayers are for you as well as his family. this is a difficult decision to be made.
I have my DNR filed with my doctor and hospital both and it will be made by my wife under the doctors advice. Hers is the same.
Our wills are in order and our houe is in order.
I would hope that more people would develope an awareness for meeting these needs.
Our best to you and hang in there. George needs his friends as well as his family.
Best to you and yours,
Bebop
