Columbia.

And very missing to nursing because when I finished my dental degree, I was thinking, all right, what I should do? I'm going to be a GP or I want to do a specialty? And I was thinking in doing maxillofacial surgery.

Okay.

And today I think about that and I was thinking, no, that was not my way.

Actually, in my first book, I have a sentence that says, who doesn't have knowledge, cut and throw away.

Who has some knowledge, treat.

Who has real knowledge, prevent.

So what's the problem?
