Good for you! There are just too many people who fail to see their deterioration and continue to push their medical envelope while putting others in danger from actions that occur due to their medical condition.
BUT I caution you not to go sit on the porch! You can still be active, work on being as healthy as you can be and live a lot longer. Look into the new continuing care facilities out their. They have all the activities you would find in a resort campground while allowing you to live in the best method that suits you. If you can live on your own they have cottages for that, if you need some food preparation or other assistance they have that. Then they are there if you need more. Again I applaud you for being forward thinking. I've already made plans for when I get to that point.
