what facial eature did Aaronson and Rutherford have in common?

They both had features that were forlorn and crumbling,

"He was a monstrous man, with a mane of greasy grey hair, his face pouched and seamed, with thick negroid lips. At one time he must have been immensely strong; now his great body was sagging, sloping, bulging, falling away in every direction. He seemed to be breaking up before one’s eyes, like a mountain crumbling."
