I remember watching the 2000 Sydney Olympics, with my nose right up to the screen, knowing there and then that I wanted a sporting career.

During an open water swim, it's easy to lose your direction. With all the splash, it can be quite hard to see the next buoy, so I look behind it for something bigger, like a tree or a building, and aim for that instead.

I raced in London in the 2012 Olympics, and it was incredible to be a part of, with half a million people watching and then later seeing kids going back to cycle.

The triathlon can be a very hard sport to train for. You see all the time when people try to improve - like their swim, for example: they train really hard for two to three weeks, and then when they go back to normal training, the swim goes back to where it was before.

When I was making 'Strong Island,' it was very clear to me that my brother's death was a point on a line that stretched back into the 1940s and beyond in my family - and in the nation.

Keep an eye on what your kids are seeing online. Parents need to stay involved in what their children are being exposed to. It's so important.

My parents were children during the Great Depression of the 1930s, and it scarred them. Especially my father, who saw destitution in his Brooklyn, New York neighborhood; adults standing in so called 'bread lines,' children begging in the streets.

I felt it was a privilege that I came from such a rich background. I had the best of both worlds. My mother was a Shia Muslim, while my father was a janoi-clad man. He never pretended to be secular.
