Christie has made his choices, he may make different ones going forward. The fact is, its his life, and it will play out however God, or fate of Vishnu or The Supreme being chooses. He may die in a car wreck tomorrow, and all your worrying about his fat comes to nothing. Of course, he could be shot at and all that fat slows the bullet and he lives...because he was fat.
Im not sure why this is such an issue for you, but understand, im not denying the research, im saying you cant paint every single person with that broad brush. Christie could outlive us both...how about we focus on the man and his accomplishments and leadership and let him and his tailor worry about his waist size
