I can still improve a lot, but there is definitely a limit to what the human body can do.

I don't even like to go out onto the streets sometimes because I can't get anything done. People want pictures and autographs all the time.

I know what to do and I go and execute.

One of the things we're trying to do more of is not just take money from corporate partnerships, but get more involved in the business side for when I retire. So Puma are going to make me an ambassador for life. I have a clothing line coming out. I am investing a lot in housing in Jamaica, buildings for rent.

I have dedicated my life to the 200m, I really love the 200m a lot.

You do not want to get married at 22! Especially if you're famous, because girls are going to be throwing themselves at you.
