I saw on wikianswers that he said in an interview that he only has seasonal allergies like everyone else cause of dust, pollen, etc. Just like everyone else but no other allergies!!! He is more and more like me in every which way... Looks, personality, goals, brains, characteristics, likes, dislikes, wants, needs, style, the only differences we have is he is 3 years older I'm a girl (thats a huge plus!) and I'm a bit shorter than him and I'm not a singer yet I will be I got to learn guitar first though lol! But we both play lefty guitar I only write with my right hand everything else is my left side being more dominant!!! Me and him are exactly alike!! :D and I didnt do anything to change myself I have always been like this before he was even famous! Ha
