Sometimes you lose sight of what's going on around you.

I don't know the history of my sport. I'm not like those people who know everything.

I don't have a clue. These things don't bother me. I think about the technical stuff but not how many steps or what my heart rate is.

Rihanna, Beyonce and Nicki Minaj - we may not win, but we would have a lot of fun [in 4x400m relay team].

I was always brought up to believe in Him [God], and to behave in certain ways. That is what my parents taught me and I always trust my parents. They have great values.

I try to focus and compete and do positive things for the sport.

If you're the Olympic champion then they have to wait four more years to get you again.
