Mysterious is the word that describes somebody who actively wants to be perceived as mysterious, Mark just wants to be private and successful. All we need to know is that he is cool. Everything he does is cool (give me an example of something he's done that's NOT cool, human relations aside). It's a very rare and very special breed of people, the ones I have a very deep affection towards. They know what they want, they respect their talent, they stay humble and grounded at all times, and they work hard. Mark deserves to be knighted more than anyone. Hopefully, one day, he'll get this recognition for a lifetime of being cool.
