You say your wife's eyesight is deteriorating. Would see rather go now so she can still see things. What are the chances that you could do a few of her bucket list now. We have friends that his wife is in very poor condition. He told her to make out her bucket list. They just got back from the west coast on a 45 day trip. How much would her work let her take off now. This is only my opinion for my wife and I. We have talked to our kids about if something happened to me. and they all said that she would be taken care of. We have medical covered so that is not a worry for her. I would rather live in a hut and not be able to spend what time we have left to enjoy our life together. No one knows when the Lord will call us home. I plan on going kicking and screaming all the way. What ever you and your wife decide, we wish you luck and enjoy each moment you have together. Memories are what are important to us, that is something that who ever survives has .
