When you live by the sea, there are definite seasons when you can see the weather coming and going, which lends itself to photography.

We spent a lot of time on the beach when I was young so I'd also take pictures of seaweed and crabs.

When you're walking onto a bus and trying to get there before the person in front of you, that's a different level of competition than playing in front of 80,000 people.

The opening ceremony was good, although I missed it.

Why go now? That is the question people asked when I announced I was retiring. A combination of things made me feel it was all drawing to a natural end.

My wife Mariana is a good photographer too and, like me, she just picks up a camera and takes a picture when she sees something, rather than looking too deeply into it.

The problem for me is that I've never actually studied photography, so it's quite a steep learning curve. Cameras these days do so much for you automatically but I still think there's a point where you should actually know the technical side.
