My name is Josefina, I am carioca. I have dedicated a lot of my time to volunteer work since I was 19. But this time it's special, it's the Olympics! This opportunity is unique! The past days have been a lot of hard work, I come to rehearse almost every day. I will be in the choreograph of the ocean in the opening ceremony, and I'm so excited to do this. On my IOP photo I will just smile and be myself.
