His mother died a couple of years ago but she was almost 100.
Looks like all the members of Chin's family live long. His 2 brothers, Louis and Mario, are over 75 and both still alive and working.

They seem to stay healthy. His mother was never sick, and Chin and his brothers are all still very active.
Louis is a reverend and Mario who got out of jail in 2004 help his brother by running the Genovese-family.

Chin is due out in 2010 when he will 82, but nobody (in the press or on the streets) has any doubts he will be back and run the family.
