In Pet Sematary, do 당신 think the same thing that happened to Louise in the end happened to Judd?

Louise was always commenting on how spry Judd was for an 83 년 old. And i was wondering if maybe he was lying about living through allot of what he lived through. Maybe he did kill Timmy Batterman, but maybe it happened a little later.
In the end of the novel, Louise was prematurely aged with white hair. Maybe the same thing happened to him that gave the appearance of old age.
