I don't think he's retired yet....says he aims to be around 330 pounds by July, so he's not playing around.
Maybe he moved to Thailand because of the way things are in the US and the spot light on steroids and the risk and stress of being a pro in the states. He has lots of business interests besides Crazy wear, probably made his cash already... To me it makes a lot of sense he moved Thailand I'm sure he gets treated like a king there, great change rate, probably cheap rent, food, drugs, women, awesome weather, I'm sure free gym etc.
