I've been around water my whole life, so I basically really learned at a young age the importance of it but also one day, at one point, clean water will be hard to find. There's so many people throughout the world that don't have access to clean water. Obviously we're extremely fortunate to have the opportunities that we have and to have all the water that we have. Like I said, and I can't say it enough, we all should work together to try and conserve as much as we possible can.

The problem with heart disease is the first symptom is often fatal.

For recovery, I think it's a big deal to eat within a half-hour after you exercise. Otherwise I just try to put carbs into my system before I swim and then load up on the protein after. I don't count calories. Whether it's Sour Patch Kids or Reese's or a bag of chips, if I feel like eating it, I'm going to eat it.

There will be obstacles. There will be doubters. There will be mistakes. But with hard work... THERE ARE NO LIMITS.

I'm pretty lazy. My wife always says, "you're the laziest, most successful Olympian I've ever seen." How does that make sense? Honestly, if I have downtime, I'm really, really good at not doing anything.

Before, it came easy for me. I don't have two speeds anymore. I need to focus on the small things that I once took for granted.

When I race, I don't think about it; it just happens.
