While they aren't immortal, there is something deeply unnatural about these zombies still walking the earth. Yes, the best medicine that money can buy is quite powerful, but cancer, Parkinson's, Alzheimer's and various other degenerative diseases are so incredibly common at their age and are mostly irreversible.

My wonderful grandmother lies, bed ridden, barely conscious in a care home, waiting for the end. And these freaks stumble around, withering before our eyes, yet always getting up again to inject a little more desperation and destruction into the world. It's so bleak and I don't know if I can stand another round of this charade.
