Looking good

From an Inspector Montalbano Mystery:

"You're looking good," said the marshal, eyeing him.
Montalbano got worried. Often of late that statement didn't sound right to him. If someone tells you you're looking good, it means they were expecting you to look not so good. And why were they thinking this? Because you've reached an age where the worst could happen overnight."
