My mom just read me a text message she got from her half-sister who is in stage 4 renal failure (or something imminently fatal like that, although I've been hearing this for about 10 years now). I was feeling sorry for her until my mom got to the point where she said she was "looking forward to meeting Jesus and Charlie Kirk".

Ignoring your actual point, something like end-stage renal disease requiring dialysis has a life expectancy of around 5 years, but even 10+ years on dialysis is not unheard of.

FWIW she has refused dialysis.

If she quit, it must've been recent. She won't last more than a couple weeks on average.
