Quotes About Senescence

According to this theory then, senile decay is simply a by-product of the accumulation in the gene pool of late-acting lethal and semi-lethal genes, which have been allowed to slip through the net of natural selection simply because they are late-acting.

Senescence is not a simple matter. Staying alive when senescence should have kicked in—it's a wonder we've done as much as we have. There's probably a purpose in senescence. Avoiding overpopulation, perhaps. Making room for new genetic material.

Take the planarian flatworm. You can slice it in two and each part will grow into a new worm. The hydra, a freshwater creature, can actually regenerate body parts, and the sea anemone doesn't appear to experience senescence at all." I

The appearance of aged persons is too well known to make detailed description necessary. The skin of the face is dry and wrinkled and generally pale. The hairs on the head and the body are white. The back is bent, and the gait is slow and laborious, whilst the memory is weak. Such are the most familiar traits of old age.

As we grow older, the memories of early life brighten, those of maturity and senescence grow dim and confused.

The evolutionary theory of senescence can be stated as follows: while bodies are not designed to fail, neither are they designed for extended operation.

The aim is to postpone frailty, postpone degenerative disease, debilitation and so on and thereby shorten the period at the end of life, which is passed in a decrepit or disabled state, while extending life as a whole.

Senescent cells can leak proinflammatory substances that make you vulnerable to more pain, more chronic illness. Eventually, many senescent cells will undergo a preprogrammed death. The

daughter, if the parents survived into senescence. This was the lot of the poet Emily Dickinson, in Amherst, Massachusetts

Age doesn't mean Maturity but Senescence

Whether the result of wear, tear, and exhaustion of resources or whether genetically programmed, all life has a finite span and each species has its own particular longevity. For human beings, this would appear to be approximately 100 to 110 years. This means that even were it possible to prevent or cure every disease that carries people off before the ravages of senescence do, virtually no one would live beyond a century or a bit more.

The very old do not succomb to disease-they implode their way into eternity. (How We Die)

I don't believe in myths of decline or myths of progress, even as regards to the literary scene. The world does not get to be a better or a worse place; it just gets more senescent. The world gets older, without getting either better or worse and so does literature.

Make your heart as good as new? Your brain? Your back? Every other part of your body that ages? That's the promise of what lies ahead with one of the major players in the longevity race: senolytics. "Senescence" means the "process of growing old," while "lytics" means "anti." Senolytics is anti–growing old.

We know in the field of aging that some people tend to senesce, or grow older, more rapidly than others, and some more slowly.

Sadly, senescent companies can't be euthanized. Instead, semi-comatose, they hang on, closing facilities, killing brands, throttling R&D, shedding staff, merging with lethargic rivals, and lobbying for regulatory help. These are "treadmill companies," and there are more of them than you think.

PATRIOTIC AND TRIBAL feelings belong to the squalling childhood of the human race, and become no more charming in their senescence.

What is to be done? We who are still half alive, living in the often fibrillating heartland of a senescent capitalism -- can we do more than reflect the decay around and within us? Can we do more than sing our sad and bitter songs of disillusion and defeat?

The general rule is that anything that is passed on in reproduction does not undergo senescence.

We've spent the last few millennia aware that senescence is horrible but knowing nevertheless that it's inevitable. We've had to find some mechanism to put it out of our minds so we can get on with our miserably short lives.

But as the cerebellum degrades with age, so does the quality of memories. The memories are there, but they're not as good.

People tend to shrink with age, especially after age 50 or so. It has to do with spaces between the joints amount of cartilage and posture. Bone length does not change.

From the window, Luke looked out over the water towers of Fifth Avenue to the park, studying the senescence of the daylight, which seemed almost viscous, ready to coagulate—trying to register that perfect moment of transition from day to evening, that instant when the light, in dying, was most nearly itself.

Organized shuffleboard has always filled me with dread. Everything about it suggests infirm senescence and death: it's a game played on the skin of a void, and the rasp of the sliding puck is the sound of that skin getting abraded away bit by bit.
