Wilhelm Ostwald Quotes

It is unlikely that changes in telomeres are influencing the lifespan of the worm. That is because telomeres only shorten when cells divide. Most of the cells of the worm stop dividing when the worm becomes an adult.

You can open up a centenarian's brain, and you'll see some areas that look like that of a 50-year-old or of a 110-year-old. You can have variation in the basic process of aging, called senescence, in different parts of the same body.

Checking your telomere length is a bit like weighing yourself: you get this single number which depends on a lot of factors. Telomere length gives a sense of your underlying health.

Aging is not one process. It's many different things going on that cause us to age. I have a program that at least slows down each of these different processes.

Aging is basically the build-up of error: error at the genetic level, error at the cellular level. Cells normally repair themselves; that's why you heal when you get a cut. But even the mechanism of repair eventually falls apart.

In humans, the thing is that as we mature, our telomeres slowly wear down. So the question has always been: 'Did that matter?' Well, more and more, it seems like it matters.

In my lab, we're finding that psychological stress actually ages cells, which can be seen when you measure the wearing down of the tips of the chromosomes, those telomeres.

Telomeres are the ends of our chromosomes that control how long we live. As telomeres become shorter, then cells age and die more quickly. In simple terms, as your telomeres get shorter, your life gets shorter.

Telomerase Activation is the single most promising approach to reversing the effects of aging.

We know that people who are born with shorter telomeres than normal also have a shorter lifespan. We know that shorter telomeres can cause a shorter lifespan.

Well, we can study aging in people, but of course those studies take decades. So what we try to do is we use simpler organisms to try and understand the basic mechanisms and so in my laboratory, for example, we use things like simple baker's yeast that we use to make bread.

If you asked me what caused aging, I would say free radicals and molecules, which spontaneously shift and form and cause damage in all our cells and genes. The body usually repairs and replaces the damage in these genes. But as you get older, the aging clock turns down those defenses.

Biological age is the key component of the aging process.

Death is an acquired trait.

So may'st thou live, till like ripe fruit thou drop Into thy mother's lap, or be with ease Gathered, not harshly plucked, for death mature: This is old age; but then thou must outlive Thy youth, thy strength, thy beauty, which will change To withered weak and grey.

But man grows old, lies down, remains where once he's laid.

Enjoy the blessing of strength while you have it and do not bewail it when it is gone, unless, forsooth, you believe that youth must lament the loss of infancy, or early manhood the passing of youth. Life's race-course is fixed; Nature has only a single path and that path is run but once, and to each stage of existence has been allotted its own appropriate quality; so that the weakness of childhood, the impetuosity of youth, the seriousness of middle life, the maturity of old age.. each bears some of Nature's fruit, which must be garnered in its own season.

When I had the youth I had no money, now I have the money I have no time, and when I get the time, if I ever do, I shall have no health to enjoy life.

The shadows of the mind are like those of the body. In the morning of life they all lie behind us; at noon we trample them under foot; and in the evening they stretch long, broad, and deepening before us.

Well...like, when you're born, you're a little baby, you're wrinkly and stuff, when you get older you sort of morph into a baby again.

The presence of a grandparent confirms that parents were, indeed, little once, too, and that people who are little can grow to be big, can become parents, and one day even have grandchildren of their own. So often we think of grandparents as belonging to the past; but in this important way, grandparents, for young children, belong to the future.

Words have longer lives than people.

Time: That which man is always trying to kill, but which ends in killing him.

Aging is not just decay, you know, its growth.

A person's life from infancy to old age is nothing else than an advance from the world towards heaven, the last stage of which is death; the actual transition from one life to the next.
