Should Pacman Retire?

Manny "Pacman" Pacquiao is a Senator in the Philippines and is a multi-millionaire. Yet still he insists on sacrificing his body and fight in the boxing ring. He has demolished a lot of monsters and legends in boxing. Morales, Barrera, Cotto, Margarito, Dela Hoya...

His most recent fight was against Thurman whom he disposed of easily.

Now, Pacman is in the talks with a potential fight with a much bigger fighter - Golovkin (GGG). GGG is a pure middleweight and could even go up in weight if he wanted to. But it seems that Pacman wants to fight this man. Do you think that Pacquiao should still fight? Or should he hang up his gloves?
