I'd rather not have my scars. Particularly the three on my back.
But if you mean being born with/natural, I'd say I'd like to be a bit taller. Being 5'8" isnt bad, its actually kinda nice. But I'd rather like to be 5'10/11" or even the even six foot. I mean, four inches isnt too selfish.
Plus, I could be a little bigger as a hockey player (though I'm just recreational right now). Even if i am just a Forward (right wing/center), being 5'8" is still kinda small. i dont need to be some giant hulking monstrosity like Zdeno Chara is (6'9"), but being a Crosby/Errey (both 5'11") or a Recchi (5'10") would be rather enjoyable and more helpful.
Then again, Steve Sullivan is only 5'8", and over his years as a player he's usually had an over 40 point season,w hich isnt all that bad.
