Dead Tired

Clint is talking with a man in the Lemon Grass Restaurante. The man says he doesn't know what's wrong with him, lately. He always seems to be dead tired. The doctors can't find anything wrong and have been prescribing vitamins and mild stimulants. He keeps having wild dreams that leave him exhausted. He's tired, but can't sleep in the daytime.
Two days later, he's dead. He died in his sleep – while driving his ATV.
