Kind of a Sad Afternoon

The thing is, I want to live as long as I can, I want to scratch for every last second on this Earth. Yet I don't want my kids to have to see me the way I see my mom. So I guess I just want to live forever, in perfect health, able to see, and hear, and remember, and perform all my bodily functions discretely, and maybe that will be enough, but it's not really all that much, is it?
