We all know that girls who compete in sports perform better in school, are physically healthier and have a stronger self-esteem.

A very sad moment for me was when my parents separated - a lot of crying, 'It's tragic, we're now a broken family, blah blah blah blah blah' - although my psychological problems stopped. I actually felt healthier.

Our thoughts really do create our lives. They've done a lot of research showing if you're an optimistic, positive person you will be a healthier person than if you're a sad, depressed, negative person.

I feel a lot healthier when I'm having sex. Physically. I feel all these jitters when I wake up in the morning. Just energy jitters. I take vitamins, I work out every day. When I'm having sex, I don't have that.

In the future, it's going to become more and more impossible for the economy to support how expensive medical care is and the number of sick people we have. Why don't we just get our population healthier so we don't need medical care?

We know that children who are healthier do not require medical treatment or care, both of which cost time and money. So, by avoiding illness, infants have a greater chance of growing into healthier children who are able to attend school and become more productive members of society.

For just a few dollars a dose, vaccines save lives and help reduce poverty. Unlike medical treatment, they provide a lifetime of protection from deadly and debilitating disease. They are safe and effective. They cut healthcare and treatment costs, reduce the number of hospital visits, and ensure healthier children, families and communities.

Surely, if knowledge is valuable, it can never be good policy in a country far wealthier than Tuscany, to allow a genius like Mr. Dalton's, to be employed in the drudgery of elementary instruction.

It seems sensible to me that we should look to the medical profession, that over the centuries has helped us to live longer and healthier lives, to help us die peacefully among our loved ones in our own home without a long stay in God's waiting room.

Using predictive models from engineering and public health, designers will plan safer, healthier cities that could allow us to survive natural disasters, pandemics, and even a radiation calamity that drives us underground.

Individuals will achieve healthier lifestyles when prevention and wellness programs are accessible and available in their workplace, through their health provider, and in their communities.

I find it a lot healthier for me to be someplace where I can go outside in my bare feet.

In general, the more food we eat in its natural state - without additives - and the less it is refined, the healthier it will be for us. Food can affect the mind, and deficiencies of certain elements in the body can promote mental depression.

Everyone would be healthier if they didn't eat junk food.

Fitness has become a way of life for me. Life is incomplete without it; it is truly the way to a healthier, happier life.

I'm excited to help people get healthier and be happier with eTone Fitness. It's been a lifesaver. I'm able to get my sweat on, have a live coach train me and get results from home. Not a gimmick, it works!

I've always believed fitness is an entry point to help you build that happier, healthier life. When your health is strong, you're capable of taking risks. You'll feel more confident to ask for the promotion. You'll have more energy to be a better mom. You'll feel more deserving of love.

The U.N. and other international bodies, along with wealthier nations, could manage the unavoidable migration from poorer countries if there were greater focus on stopping the larger chaos created by leaders who finance and support terrorism in the name of Islam.

People who believe they have the power to exercise some measure of control over their lives are healthier, more effective and more successful than those who lack faith in their ability to effect changes in their lives.

Just because you're struggling with self-discipline doesn't mean you have to raise the white flag and declare your self-improvement efforts a complete failure. Instead, work to increase the chances that you'll stick to your healthier habits - even when you don't feel like it.

If we allow responsible management of our forests and end the nonsense litigation from radical environmental groups, we can get our timber mills up and running, reduce the risk of wildfires, and ensure healthier forests and cleaner air.

We all recognize that in recent decades, many important achievements have helped create a cleaner, healthier environment, yet our national needs in environmental health are not being fully met.

Because I dieted so much in the past, I just can't diet again. It's something I don't want to do and I don't even know if I am capable of. I think it's a much healthier and happier way to live.

I was so young when I was competing that I wasn't as focused on my diet. I was a kid - I ate a lot, and I worked out a lot. But as I get older, I definitely want to be healthier.
