That feels not that medical.
Like have you met someone of old age? They have lots of stuff that's very specific and quite nasty.
Your obituary isn't gonna say you "died of old age." It's gonna say you died of like acute pulmonary polyps.
My grandpa is gonna go any day now. And I bet all the money in my account – mostly his money from Christmas if we're being honest – the doctor isn't gonna go "Sorry, he just got up there in years. Nothing we can do about it."
