CD (I hope he's okay with me calling him that... *swoon*) also has one more trick he says keeps him looking young. He doesn't take long baths late at night or early in the morning. He keeps dry. Maybe that's why everyone around him always seems so thirsty.
Of course a lot of diligence and hard work goes into maintaining this appearance, but a lot of it is just good luck. He inherited some fantastic genes from his parents. One of whom I think this picture confirms must have been angelic in origin.
