He. Is. Amazing. What I love is the total love and respect the rest of the family have for him "I wouldnt want to disappoint Carlise" "Carlise was right" even Bella considers his opinion to be the most importnat.
I think with the cold hands thing, yep most doctors have cold hands. Its one of those running jokes isnt it? My question would be "does he have bad handwriting?" beacuse THAT would be a giveaway if he had beautiful script like Edward!
Also if your ill in hospital its likely you may have a temperature so the cool hands would actually be soothing and you'd be less likely to question it.
He also seems to have such a wonderful gift for medicine. I'm like Bella - faint at the smell of blood (though touchwood luckily not as accident prone!) but I think like her I could cope if her were my doctor - hes so calm, methodical and understanding.
I know not quite relevent but I didnt picture him as so good looking when I read the books and when I saw the film he was one of the few characters I was happy didnt look how I imagined - gave me a much better perspective!
