I've got everything I wanted so I'm just happy.

Unfortunately, I don't usually get to see much outside the Olympics as I compete almost every day. I have been to Rio a few times and got a tour of the sites. It is a spectacular city.

Messi or Cristiano - Speed? Cristiano. Shot? Cristiano. Dribbling? Messi. Intelligence? Messi. Talent? Messi. Winner is Messi!

Everyone has the right to their own opinion.

I want to be one of the greatest athletes ever to live, not only in track and field, but in all of general sport.

When people contact me on Instagram or Facebook, kids and adults, who say, "You're an inspiration. You make me want to work hard to achieve my goals." If I can still do that after I retire that makes me feel good.

I can still improve a lot, but there is definitely a limit to what the human body can do.
