I have always stayed out of politics, I don't believe it would be appropriate to talk about it.
There are younger, stronger swimmers coming up and they are hungry. I can't influence what they do, I only know what I can do and I know how greedy I am to defend my title.

In athletics, older runners tend to go for longer races, but it's the opposite in swimming because your body can't handle the endurance.
