Welp, quite a firestorm of comments on the Vino post below. But I have to hand it to my brother who had the following to say:
I am completely cynical: any 'miraculous comeback' must mean doping. Think Armstrong, Landis, Vino. The next big doping scandal? Two words: Harry Potter. Man, he came back from death itself! Impossible without 'assistance'. And I hear Skeeter's book has a section about Dumbledore's youthful friendship with Ferrari.
I Knew it: Harry freekin Potter, boy doper!
