If we can continue to come together and work on small things little by little, at least it's something. It's a start. At least now there's a lot more talk about climate change and the Earth's state than when I was a kid. I guess it's better late than never? But it's also very tricky because this is something that's so important to so many of us, and a lot of people don't see it that way. But hopefully, we can get all our points across to them - one by one, one person at a time.

My little son is already like me - my mom has always said I used to bounce off the wall and never stop talking or sit still. I'm starting to see that with him. I guess it's living proof he's part of me.

So, you know, if, if I wanted to get up and just play golf one day, I would just get up and play golf. If I wanted to go to Vegas, I would just get up and go to Vegas.

I want to be able to look back and say, 'I've done everything I can, and I was successful.' I don't want to look back and say I should have done this or that. I'd like to change things for the younger generation of swimmers coming along.

This is my 20th year in the sport. I've known swimming and that's it. I don't want to swim past age 30; if I continue after this Olympics, and come back in 2016, I'll be 31. I'm looking forward to being able to see the other side of the fence.

I'm the same kind of guy before all this happened.

It's not how you start, but it's how you finish.
