Whether they would have prospectively desired at the time to die in their sleep 10 years earlier, on the other hand, is something we can objectively measure... because suicide is a thing that exists. Did they?
Signs point to no.
Mind you, some would bin that in with the douchey "I wouldn't want to live if I became paraplegic/deaf/blind," but I do fear that, given how crappy it is to be 75 today, it's not going to be senior Disneyland by the time I'm old. Older.
Put my brain in a jar and I might have a different perspective, but I've seen enough family members admit they're just tired and want to go when their time comes.
My dad is over 70 and is completely fit, healthy, independent and pain free. Sure, not all old people have it so good, but with increased live expectancy comes increased quality of life at older ages
Young people always think we want to live longer. Somehow, our minds end up changing by the time we become old people.
No they don't. Old people might say they wish they'd died younger, but their actions show otherwise.
Those actions?
But yes, if somebody makes a failed suicide attempt, and doesn't follow up on that, I'd say that they wish to live (except for those who are left physically incapacitated due to their attempt, obviously).
So you might get to see your kids graduate high school, if you have them young enough. Very high chance their kids never meet grandma/grandpa, and they almost certainly won't be old enough to remember.
