As long as I’m of sound mind and capable body, I’m fine with it, but not at any cost. I’d rather shuffle off this mortal coil than drag out the suffering of immobility and / or dementia.

I think Atul Gawande’s “Being Mortal” is good required reading. Among other things, he talks about the smoke and mirrors of our species’s increased lifespan. (i.e. increased lifespan, yes, but too often at the cost of diminished quality of life through those additional years.)
