How did he die of a heart attack?
There are people out there who outweigh him and are like blob fat, small shoulders, no shape. I know he was not exactly a varsity athlete but he was not bloated fat either. He had a massive frame, carried his weight like a boss and was a big man but he was not like a dough fat.
So do people who are built like blobs live to 70 and 80 and James Gandolfini died so relatively young.
