The very concept of an old age home is new to India. An old age home is usually the place, a home for those old people who have no one to look after them or those who have been thrown out of their homes by their children.
Ageing versus immortality[ edit ] Immortal Hydra, a relative of the jellyfish Human beings and members of other species, especially animals, necessarily experience ageing and mortality.
Fungi, too, can age. Early life forms on Earth, starting at least 3. Such organisms prokaryotes, protozoans, algae multiply by fissioning into daughter cells; thus do not age and are innately immortal.
The sexual organism could henceforth pass on some of its genetic material to produce new individuals and could itself become disposable with respect to the survival of its species. A number of characteristic ageing symptoms are experienced by a majority or by a significant proportion of humans during their lifetimes.
Dementia becomes more common with age. Furthermore, many types of memory decline with ageingbut not semantic memory or general knowledge such as vocabulary definitions, which typically increases or remains steady until late adulthood  see Ageing brain.
Intelligence declines with age, though the rate varies depending on the type and may in fact remain steady throughout most of the lifespan, dropping suddenly only as people near the end of their lives. Individual variations in rate of cognitive decline may therefore be explained in terms of people having different lengths of life.
Senescence year-old woman holding a five-month-old boy At present, researchers are only just beginning to understand the biological basis of ageing even in relatively simple and short-lived organisms such as yeast. A model organism for studying of ageing is the nematode C.
Programmed factors follow a biological timetable, perhaps one that might be a continuation of the one that regulates childhood growth and development.
This regulation would depend on changes in gene expression that affect the systems responsible for maintenance, repair and defence responses.
Damage-related factors include internal and environmental assaults to living organisms that induce cumulative damage at various levels. It is likely that most of these pathways affect ageing separately, because targeting them simultaneously leads to additive increases in lifespan.
For example, numerous perennial plants ranging from strawberries and potatoes to willow trees typically produce clones of themselves by vegetative reproduction and are thus potentially immortal, while annual plants such as wheat and watermelons die each year and reproduce by sexual reproduction.
In it was discovered that inactivation of only two genes in the annual plant Arabidopsis thaliana leads to its conversion into a potentially immortal perennial plant. In laboratory settings, researchers have demonstrated that selected alterations in specific genes can extend lifespan quite substantially in yeast and roundwormsless so in fruit flies and less again in mice.
Some of the targeted genes have homologues across species and in some cases have been associated with human longevity. The strong effect of age on DNA methylation levels has been known since the late s. DNA methylation age of blood predicts all-cause mortality in later life. This resetting into a juvenile state was experimentally achieved by activating the four Yamanaka DNA transcription factors — Sox2Oct4Klf4 and c-Myc which have previously been routinely used for producing young animals from cloned adult skin cells.
In humans and other animals, cellular senescence has been attributed to the shortening of telomeres at each cell division ;  when telomeres become too short, the cells senesce and die or cease multiplying.
Sirtuin in turn inhibits mTOR. When organisms restrict their diet, mTOR activity is reduced, which allows an increased level of autophagy.
This recycles old or damaged cell parts, which increases longevity and decreases the chances of being obese. This is thought to prevent spikes of glucose concentration in the blood, leading to reduced insulin signalling.
This has been linked to less mTOR activation as well. Therefore, longevity has been connected to caloric restriction and insulin sensitivity inhibiting mTOR, which in turns allows autophagy to occur more frequently.
It may be that mTOR inhibition and autophagy reduce the effects of reactive oxygen species on the body, which damage DNA and other organic material, so longevity would be increased. Many have argued that life span, like other phenotypesis selected.
Traits that benefit early survival and reproduction will be selected for even if they contribute to an earlier death.This paper provides an overview of theory in religion, aging, and health.
It offers both a primer on theory and a roadmap for researchers. Four “tenses” of theory are described—distinct ways that theory comes into play in this field: grand theory, mid-range theory, use of theoretical models, and positing of constructs which mediate or moderate putative religious effects.
Growing older for sure brings on more responsibility! Making sure I am healthy is Disabilities Growing Old: An Overview by Tamar Heller Most people with intellectual and developmental disabilities (I/DD) have a experience age-related changes.
In com-parison with adults without long-term disabilities, adults with I/DD are more.
1. Preliminaries. If ethics is widely regarded as the most accessible branch of philosophy, it is so because many of its presuppositions are self-evident or trivial truths: All human actions, for example, serve some end or purpose; whether they are right or wrong depends on an actor’s overall aims.
Perfect World brings players the concept of 3D online game with the theme creating a world for the first time, giving players a new experience in team work and world creation.
In old age, one's experience is almost a mirror image of what it was earlier as the body deteriorates and one needs to learn to accept it. In ''play age'' or preschool children, what is being learned is a sense of initiative and purpose in life, as well as a sense of playfulness and creativity, the theory holds.
