Where to the old crooks go?

An old man was busted for trafficking hundreds of thousands of pills. 80 Years old. Below is the link. (it may expire after some time)

This leads me to the question, where do old crooks go? What happens when an old man of 80 commits a crime that gives him 20 in the slammer. Do they have a location they move the older prisoners to? Whats it like?

Maybe they gather during lunch in the cafeteria and plan a break-out. I would think it would be something like the movie "Cocoon". How dangerous is an older criminal to society.

Am I wrong in remembering or thinking that organized crime is usually ultimately run by an older criminal? Like "Papa Primavera" or "Uncle Louie" or "The Old Man". (See Boondock Saints 2).

Just curious?
