It's torturous what my siblings put me through. I can take any Olympic final, I can fight in a world championship and fall behind and win in sudden death, but when it comes to my siblings, it's out of my control. There's not much I can do.

The statistics show that when you've done something for so long, it'll either be, yeah, you're slowing down, or someone's doing it better. But physically, I feel great. More than that, it's mental and spiritual.
