The 'Night Train' has already been a crazy ride for me. We flew around making TV appearances and stadium announcements all over the country, fueled by little more than coffee and adrenaline... so many fans jumped on board with us, and I couldn't be more thankful.

Museums are like sports stadiums, hotels and hospitals: they are in the category of captive-audience dining.

I love sports - I am a die-hard fan of soccer, and I am always at Maracana Stadium in Rio watching Flamengo play. I am also a big fan of basketball; I stay up at night to watch Lebron James play whenever I can.

In New York, I have a photo of my parents on their wedding day in 1947. They're beaming at home plate in Houston's Buffalo Stadium. I love the photo because my dad is smiling. He didn't smile much in his later years.

Science has taught us, against all intuition, that apparently solid things like crystals and rocks are really almost entirely composed of empty space. And the familiar illustration is the nucleus of an atom is a fly in the middle of a sports stadium, and the next atom is in the next sports stadium.

Procedures outside the stadiums and in the parking areas still need to be optimized, for example so that emergency medical services can leave the grounds on their way to the hospital faster.

There's something magical about a home run. It almost violates the space of the stadium. It's a game of the imagination in some ways. Baseball.

Confronting a stadium audience, you can't see the whites of their eyes. It's just an amorphous mass of noise and, of course, you can't see the alleged billions watching at home either, so the degree to which you are intimidated is quite low.

We knew it was going to be the biggest event scheduled in the history of women's sports, but we didn't ever fathom we would be playing before sold-out stadiums all over the country.

I remember the great atmosphere and the great stadium.

The final upshot of thinking is the exercise of volition, and of this thought no longer forms a part; but belief is only a stadium of mental action, an effect upon our nature due to thought, which will influence future thinking.

It's much easier to be successful than it is to be relevant. The tricks won't keep you relevant. Tricks might keep you popular for a while, but in all honesty, I don't know how U2 will stay relevant. I know we've got a future. I know we can fill stadiums. And yet with every record, I think, 'Is this it? Are we still relevant?'

Doing nothing would stress me out. So I am still pretty much active practicing judo with my friends, who are former judo athletes, to maintain our fitness as well as the friendships among us. In my spare time, I usually go jogging around the Gelora Bung Karno stadium or head to the gym.

Yankee Stadium, and the Yankees are so famous for Mickey Mantle, Joe DiMaggio, Lou Gehrig, all of those guys.

The psychology of sport is so important. When you are standing at the crease, in front of a stadium full of people, it's a pretty intense experience. So you need to have the psychological tools to control your mind and deliver your best performance.

My heroes, my dreams, and my future lay in Yankee Stadium. And they can't take that away from me.

Whether that was in the Chepauk Stadium in Madras or at the Ilford Cricket School, there was a daily diet of cricket run by my dad. It was a hard school but he knew what he was doing. Everything I achieved was down to my dad.

The 'Bird's Nest' National Stadium, which I helped to conceive, is designed to embody the Olympic spirit of 'fair competition.' It tells people that freedom is possible but needs fairness, courage and strength.

Ego is hilarious - especially the vanity of a comedian. As soon as you see one start worrying about how cool he is or about how many stadiums he can fill, he stops being funny.

Everything I've been thinking, every vision, even down to every shot I throw, it just ends up here in reality. Whether it was in a fight and how to react or whether it was in a stadium with screaming fans or whether I was in a fancy car or the best clothes ever, I always put myself somewhere.

I'm a humungous Browns fan. My 30th birthday was actually at the Browns' stadium.

The Santiago Bernabeu is an amazing stadium.

There's an amazing intimate feeling in a small club but an insane rush playing a stadium or festival.

There is such a rich sporting culture in Western Sydney, one that nurtured my sporting aspirations. Having Penrith Whitewater Stadium right at my doorstep was such an amazing advantage. It was a springboard to my success as an athlete, and I feel really fortunate to have grown up in this part of the world.
