I haven't been able to talk to my grandfather, or hear his stories, or learn about him, or share anything with him, or even be a part of his life for at least 5 years now. He will probably be "alive" for another five years. He mostly just coasts through life. He doesn't really get to interact with friends, because the ones that aren't dying, he doesn't remember. When I see him, he asks me about graduating high school, which I did over a decade ago now.

I doubt he would choose to die, but when I get to experience the exact same thing in 40 years, I'm pretty sure I'd rather chew on a 12 gauge. Having a more reliable and less terrifying option is important.
