I get letters every year from women who think Valentine's Day is an empty exercise, but are ironically pretty exercised when their boyfriends neglect or forget it.

A memoir forces me to stop and remember carefully. It is an exercise in truth. In a memoir, I look at myself, my life, and the people I love the most in the mirror of the blank screen. In a memoir, feelings are more important than facts, and to write honestly, I have to confront my demons.

I repeat... that all power is a trust; that we are accountable for its exercise; that from the people and for the people all springs, and all must exist.

Depend upon yourself. Make your judgement trustworthy by trusting it. You can develop good judgement as you do the muscles of your body - by judicious, daily exercise. To be known as a man of sound judgement will be much in your favor.

Because I travel so much, I bring my workout clothes and shoes wherever I go. That way I can always do some exercise.

Often, I'll do a quick workout in my hotel room consisting of exercises for the legs, glutes, abs, and arms with my own body weight. Also, I always have a jump rope, a medicine ball I can inflate, and a band in my suitcase. It's a great kit to have for travel.

When I'm in London I do have the convenience of being close to St James Park which is also good for me because it gives me an excuse to get out and get some much needed exercise!

I get pretty much all the exercise I need walking down airport concourses carrying bags.

Wearable technology will tell us how well we are sleeping and whether we need to exercise. Sensors in the street will help us avoid traffic jams and find parking. Telemedicine applications will allow physicians to treat patients who are hundreds of miles away.

The demographic weight of countries such as China and India exercise a massive pressure on our wages and salaries. They have accomplished massive technological advances and the revolution in information technology has reduced the costs of transport.

As a teacher at Princeton, I'm surrounded by people who work hard so I just make good use of my time. And I don't really think of it as work - writing a novel, in one sense, is a problem-solving exercise.

I was never a class clown or anything like that, but I do remember being in the first grade and my teacher, Mr. Chad, told the class one day that we were going to do some exercises. He meant math exercises, but I stood up and started doing jumping jacks. To this day, I don't know what possessed me to do that, but all my friends cracked up.

Tribes don't need Congressmembers' sympathy. What tribes need is for us to properly exercise our duty.

Weight-bearing exercise builds bone density, builds your muscular strength so that you can hold your body up where those bones have a tendency to get weak.

So many older people, they just sit around all day long and they don't get any exercise. Their muscles atrophy, and they lose their strength, their energy and vitality by inactivity.

I've always loved sports and hockey is a sport I play as much as I can. I love it. In a weird way it's like church and therapy and exercise all rolled up into one. I mean when I play hockey I don't think about anything.

The main thing is healthy eating, exercise, which I do for special events, like if it's Sports Illustrated, or the swim suit catalogue for Victoria's Secret, or my own calendar that I did for the year 2000.

It's too bad that one has to conceive of sports as being the only arena where risks are, for all of life is risk exercise. That's the only way to live more freely, and more interestingly.

I like sports, and swimming is my favorite. Doing physical exercises keeps one fit and healthy and helps one work more efficiently. I think we all need to strike a balance between work and relaxation. This can keep us energetic and help us do our job better.

That sacred space of conscience where you can exercise your rights in terms of religious freedom and deeply-held, reasonable beliefs is the core of human dignity. In fact, that's the basis for civilization itself. And when you lose that fundamental principle... you have no basis on which to build.

We need society, and we need solitude also, as we need summer and winter, day and night, exercise and rest.

I know of no safe depository of the ultimate powers of the society but the people themselves; and if we think them not enlightened enough to exercise their control with a wholesome discretion, the remedy is not to take it from them but to inform their discretion.

In England, an inventor is regarded almost as a crazy man, and in too many instances, invention ends in disappointment and poverty. In America, an inventor is honoured, help is forthcoming, and the exercise of ingenuity, the application of science to the work of man, is there the shortest road to wealth.

At a time when 2500 American soldiers have given their lives for the cause of bringing democracy to Iraq, it is sad and frustrating to watch the Republican establishment disgrace the exercise of democracy in our own House of Representatives.
