Which of these descriptions fit Conan best ?

[MrDetective]

is Conan an intelligent boy who happens to be a detective

or is he a detective who happens to be very intelligent ?

[k11chi]

detective who happens to be very intelligent because we know he wanted to be one since he was kindergarten aged

[KaitoRizu]

I don't think any of them is more fitting than the other because intelligence is a "trait" that he has while being a detective is an "ambition" or a "job" not a "trait"...
he was born intelligent but he wasn't born a detective, he just decided to become a detective at a certain point in his life...
I hope I could deliver my point well...
