"I've never lifted a single weight in my life." — Michael Phelps

For the millionth time, I'm retired. I keep saying it, and people keep answering, 'Well, maybe he doesn't mean it this time.' But I do.

I want to retire how I want to retire - and I have a great opportunity to do that.

And, you know, being able to wear the stars and stripes, when you step up on one of the blocks or, you know, when you step off of an airplane or when you hear the national anthem play, you know, it's one of the greatest feelings in the world because you know that there are people at home who are supporting you and watching you.

I know it won't be eight medals again. If you want to compare me to that, that's your decision, not mine. I'm going out there to try to accomplish the things that I have in my mind and in my heart.
