I believe part of the reason he's not aging as fast is that he's gotten healthier to meet the demands of the role. He said that he completely changed his diet, gave up alcohol, and joked that he worked out more in the 6 months leading up to the first AM than he had in the previous 15 years. With him having to do CW, AM&W, and IW 2 so close together, he's probably maintained that healthy living.I still can't believe Paul Rudd is almost 50, he looks so young.
