Eight Nosy Questions

When the whole world is writing about someone like Michael Phelps, you tend to get a lot of overlap. If you've been following the Olympics by now, you probably know the basics: Phelps grew up just outside of Baltimore, and battled ADHD as a kid. He was raised mostly by his mother, Debbie, a middle school principal. You might feel as if you've heard those details hundreds of times by now. But that isn't everything you need to know about Phelps. In fact, here are some things you never knew.

1. He wears two caps

This is actually something a lot of swimmers do, and it's probably more psychological than anything. The goal is to make your head as smooth as possible and thus be able to move through the water faster. When races are decided by hundredths of a second, swimmers will try to get any advantage. Mostly, it simply feels more secure.

2. Erik Vendt, not Ryan Lochte, is his closest friend

Phelps and Lochte are pals -- they have a shared interest in music, women, life -- but they never talk about swimming. They're too competitive. Vendt, who trained with Phelps the last two years in Michigan, was one of his closest confidants during this difficult year that included uneven training and a broken wrist. They're also roommates during most meets.

3. He wears

different suits for different events

When you watch Phelps swim the freestyle events, he usually wears the kind of Speedo LZR Racer that has straps over his shoulders and goes all the way down to his ankles. But when he swims an event where he needs to perform the butterfly stroke, he only wears the LZR Racer pants. Because so much shoulder motion is required for the fly, he feels more comfortable without something over his shoulders. You'll also see him in the relays immediately unzip his suit and pull it off his shoulders and down around his waist. It's not a vanity thing; it's because the suits are ridiculously tight and most swimmers want to unzip as soon as possible.

4. He rarely reads what's written about him

Phelps stopped reading about himself long ago. His coach Bob Bowman, on the other hand, reads everything. "I'm a big Google guy," Bowman says.

5. It's not always hip-hop on his iPod

This week Phelps has been listening to Lil Wayne, a rapper from New Orleans. He's also a big fan of artists such as Rick Ross, Young Jeezy and, of course, Jay-Z. But occasionally he'll mix things up and listen to some techno.
