We designed a number of features from the ground up, like custom display and optics technology with very high refresh rates and pixel density. We added integrated 3-D audio, a built-in microphone so you can speak to friends inside virtual worlds, and precise mechanical adjustment systems.

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.

The density of space junk peaks around 620 miles up, in the middle of so-called low-Earth orbit. That's bad, because many weather, scientific, and reconnaissance satellites circle in various low-Earth orbits.

I think it's going to be a very important, unique data set in terms of measuring the behavior of your lower body in space and trying to figure out what we can do to preserve bone and muscle density.

Without strong health systems in place, the higher the population density, the more difficult it becomes to prevent and control outbreaks, and not just because of the increased risk of contagion.

The smaller the planets are, they are, other things being equal, of so much the greater density; for so the powers of gravity on their several surfaces come nearer to equality. They are likewise, other things being equal, of the greater density, as they are nearer to the sun.

A high nutrient density diet was associated with more feelings of hunger in the mouth and throat and less in the head and stomach.

Your future health can be predicted by the nutrient density of your diet.

Less cars on the road means productivity and jobs growth, as it allows for the more efficient movement of goods and services and encourages greater urban population density.

Certain kinds of speed, flow, intensity, density of attacks, density of interaction... Music that concentrates on those qualities is, I think, easier achieved by free improvisation between people sharing a common attitude, a common language.

Eric's Trip is still a huge influence on me. The style of those recordings and the rawness of them is very inspiring. And the density of the distorted parts, amazing.

Here is Menard's own intimate forest: 'Now I am traversed by bridle paths, under the seal of sun and shade...I live in great density...Shelter lures me. I slump down into the thick foliage...In the forest, I am my entire self. Everything is possible in my heart just as it is in the hiding places in ravines. Thickly wooded distance separates me from moral codes and cities.

"The theological perspective of participation actually saves the appearances by exceeding them. It recognizes that materialism and spiritualism are false alternatives, since if there is only finite matter there is not even that, and that for phenomena really to be there they must be more than there. Hence, by appealing to an eternal source for bodies, their art, language, sexual and political union, one is not ethereally taking leave of their density. On the contrary, one is insisting that behind this density resides an even greater density ? beyond all contrasts of density and lightness (as beyond all contrasts of definition and limitlessness). This is to say that all there is only is because it is more than it is. (...)

Regardless of the staggering dimensions of the world about us, the density of our ignorance, the risks of catastrophes to come, and our individual weakness within the immense collectivity, the fact remains that we are absolutely free today if we choose to will our existence in its finiteness, a finiteness which is open on the infinite. And in fact, any man who has known real loves, real revolts, real desires, and real will knows quite well that he has no need of any outside guarantee to be sure of his goals; their certitude comes from his own drive.

He had come to that moment in his age when there occurred to him, with increasing intensity, a question of such overwhelming simplicity that he had no means to face it. He found himself wondering if his life were worth the living; if it had ever been. It was a question, he suspected, that came to all men at one time or another; he wondered if it came to them with such impersonal force as it came to him. The question brought with it a sadness, but it was a general sadness which (he thought) had little to do with himself or with his particular fate; he was not even sure that the question sprang from the most immediate and obvious causes, from what his own life had become. It came, he believed, from the accretion of his years, from the density of accident and circumstance, and from what he had come to understand of them. He took a grim and ironic pleasure from the possibility that what little learning he had managed to acquire had led him to this knowledge: that in the long run all things, even the learning that let him know this, were futile and empty, and at last diminished into a nothingness they did not alter.

Clare, I want to tell you, again, I love you. Our love has been the thread through the labyrinth, the net under the high-wire walker, the only real thing in this strange life of mine that I could ever trust. Tonight I feel that my love for you has more density in this world than I do, myself: as though it could linger on after me and surround you, keep you, hold you.

My workouts include aerobic exercise for a healthy cardiovascular system strength training to maintain muscle tone and bone density core strength exercise for a stable mid-section and stretching to maintain mobility.

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.
