I am as non-accepting of medical quackery and unscientific approaches as anybody else. I've grown up as a card-carrying scientist, and I know the power of science to answer questions, and for many questions I don't know of anything better than scientific approaches to answer them.

Let's all be more humble about the evidence behind medical advice but also respect the challenges to providing accessible lifestyle guidance.

Reimbursement is a major determinant of how medicine is practiced. When reimbursement changes, so do medical practice and medical education.

If you're with a close friend, your anger may raise his blood pressure as well as your own, whereas loving feelings may lower blood pressure in both of you.

No one has all the answers, so whatever a woman who has the BRCA mutation chooses to do requires courage and an element of faith. And a lot of love and support.

In 2010, I consulted with President Clinton after his bypass grafts occluded and encouraged him to make healthy lifestyle changes including a whole-foods, plant-based diet low in refined carbohydrates.

The choices you make each day in your diet and lifestyle have a direct influence on how your genetic predisposition is expressed - for better and for worse. You're only as old as your genes, but how your genes are expressed may be modified by exercise, diet and lifestyle choices much more than had previously been believed - and more quickly.

If you're at high risk or are trying to reverse heart disease or prevent the recurrence of cancer, you probably need to make bigger changes in diet and lifestyle than someone who just wants to lose a few pounds and is otherwise healthy. If you just want to lower your cholesterol, weight or blood pressure, begin by making moderate changes.

Small changes in diet don't have much effect on preventing coronary heart disease and cancer. But bigger changes in diet and lifestyle may prevent heart attacks in almost everyone.

When most people think about my work, they think about diet. To me, diet has always been the least interesting part of it.

Whether you're six or sixty, if you go on a diet and lifestyle program and feel constrained, you're likely to go off it sooner or later. Offering a spectrum of choices is much more effective; then, you feel free and empowered.

If we can reach populations in developing countries and help them understand the value of their indigenous diet and lifestyles rather than copying ours, perhaps we can reverse the exponential rise in cardiovascular disease that is plaguing them.

Not everything that lowers HDL is bad for you. If you change from a high-fat, high-cholesterol diet to a healthy low-fat, low-cholesterol diet, your HDL levels may stay the same or even decrease because there is less need for it. When you have less garbage, you need fewer garbage trucks to remove it, so your body may make less HDL.

As a veteran of the diet wars, I think it's time to call a truce. Rather than hear experts argue, most people want practical information they can use.

If you go on a diet and feel constrained, you are more likely to drop it. But if you see your food choices each day as part of a spectrum, then you are more likely to feel free and empowered.

Although many people believe that the primary emphasis of my work is about diet, it's not. What we eat is important, of course, but what comes out of our mouth may be more important than what goes into it.

The need for connection and community is primal, as fundamental as the need for air, water, and food.

The need for love and intimacy is a fundamental human need, as primal as the need for food, water, and air.

So when I got to be about 13 or 14, I started listening - even though my parents music was way cool - to contemporary hard rock at that time, which was Aerosmith, Cheap Trick, Black Sabbath, AC/DC, Ted Nugent and all that, and that's just where I came from.

You know, when you really connect with the instrument and everything just comes out on an emotional level very naturally through your playing. That's, you know, a great night. And I think the reason I love touring so much is you're chasing that high around all the time, trying to have another good night.

Guitars are like women. You'll never get them totally right.

As for Guns N' Roses, I don't think there's ever a chance of a reunion.

Our career is a dream. I mean, we get to act, travel around the world, and meet cool people. What's not to love!

Australia is so cool that it's hard to even know where to start describing it. The beaches are beautiful; so is the weather. Not too crowded. Great food, great music, really nice people. It must be a lot like Los Angeles was many years ago.

I'm definitely bicoastal, but I have to say, it's easier to live in New York than in L.A. I feel like people respect other people's space a bit more here. Everyone has the right to that freedom, right? Everyone has that right. It's freezing in New York right now. In L.A., it's sunny. But I would choose freezing over being followed.

I like to go to parties where I know everyone. How are you going to have fun with people you don't know?

When you're walking down the street, or you're at a restaurant, someone catches your eye because they have their own look. It goes way beyond what they're wearing - into their mannerisms, the way they smile, or just the way they hold themselves.

There are just some really beautiful people in the world. When you're walking down the street, or you're at a restaurant, someone catches your eye because they have their own look. It goes way beyond what they're wearing - into their mannerisms, the way they smile, or just the way they hold themselves.

You can be cool and at the same time respect your woman, who will hopefully become your wife, who will hopefully become the mother of your kids. America needs to get back to family values.

I'm most proud of the blessings that God has bestowed upon me, in my life. He's given me the vision to truly see that you can fall down, but you can still get back up. Hopefully I'll learn from my mistakes and have the opportunity to strengthen and improve the next thing I do.

I hate it when people come up to me on trains and ask 'Are you Soulja Boy?' If people want pictures or autographs, that's cool, but I don't like the dumb questions.

When I was in Japan on tour in 2010, I felt like I was 30 years into the future. I love technology and they are so advanced with their phones, computers, everything. I think they had the iPhone way before we did in the U.S. I love gadgets, games, social media and I try to stay ahead on all that stuff, but they get it all first.

I don't travel anywhere without the PS3 and XBox. There's nothing better to do on long bus trips while on tour.

Oh yeah; I love when I'm writing something that makes me cry - that's so cool. If it got me to do that, it's going to get someone else to do that.

I have a good imagination. Look, I know what it feels like to have a broken heart. I know what it feels like to feel something for somebody. I'm just too weird to be in a relationship.

I haven't left the house without a packet of Kleenex in my back pocket for as long as I can remember. Whenever I start thinking I'm incredibly cool, the packet of Kleenex in my back pocket brings me right back down to earth.

When I go to movies and I love the movie, it's because it feels like it articulated something about how we're living now, and also gives me some insight into my own life. I feel actually altered after having seen it.

In the Middle East in the summertime, to keep cool, a lot of people sleep on the rooftops.

Music is an emotion, and I put it out there.

People expect you to be doing something cool all the time. In a normal life, that's not happening!

Modeling is really what I do during my free time. It's fun for me, so it doesn't feel like work. I choose to do it.

My mom is very much about 'less is more.' She showed me how to use makeup to enhance your beauty but not to change your face, which I think is important.

A lot of people ask me what my mom has taught me about modeling. The truth is the things she teaches me go deeper than what pose to make or what my good side is.

I wasn't the cool kid in school, but I wasn't the lame one. I knew I wasn't cool, so I called myself lame, and that's what made me cool in front of the cool kids.

Don't let people see when you're mad - just smile and laugh.

There is something exciting about being in an environment in which it's really cool to be smart.

My mother was an English teacher who decided to become a math teacher, and she used me as a guinea pig at home. My father had been a math teacher and then went to work at a steel mill because, frankly, he could make more money doing that.

Placebo is music for outsiders, by outsiders and our gigs are like conventions of outcasts, which is cool.

That was like my safe place with great teachers where everyone could let down their guard and not feel judged. As soon as we walk outside, it was like, 'Look at these weird drama club kids.' But we all had our own agreement that we were cool in our own way.

It's been constant grinding and trying to secure work that I care about, tireless auditions and meetings. I've been fortunate that a lot of cool doors have opened to me, chiefly meeting great people who were inspired by what I've done and what they feel I could bring to their projects.
