Unlike other "accelerated aging diseases", such as Werner syndrome, Cockayne syndrome, or xeroderma pigmentosum, progeria may not be directly caused by defective DNA repair. These diseases each cause changes in a few specific aspects of aging but never in every aspect at once, so they are often called "segmental progerias".
Thelema (/ θ ə ˈ l iː m ə /) is a Western esoteric and occult social or spiritual philosophy [1] and a new religious movement founded in the early 1900s by Aleister Crowley (1875–1947), an English writer, mystic, occultist, and ceremonial magician. [2]

The research shows that even gradual changes can improve heart health and slow down aging, Makarem said. “The cool thing is there are eight health factors and behaviors that are modifiable ...
Geriatrics, or geriatric medicine, [1] is a medical specialty focused on addressing the unique health needs of older adults [2] The term geriatrics originates from the Greek γέρων geron meaning "old man", and ιατρός iatros meaning "healer". It aims to promote health by preventing, diagnosing and treating disease in older adults. [3]
The metabolic stability theory of aging suggests it is the cells ability to maintain stable concentration of ROS which is the primary determinant of lifespan. [37] This theory criticizes the free radical theory because it ignores that ROS are specific signalling molecules which are necessary for maintaining normal cell functions. [37]
In 1968 it took the form and became known as the neuroendocrine theory of aging. [38] [39] [40] 1956 Denham Harman proposed the free-radical theory of aging and demonstrated that free radical reactions contribute to the degradation of biological systems. [41] The theory is based on the ideas of Rebeca Gerschman and her colleagues put forward in ...
Normally, developing societies have lower life expectancies in comparison to developed countries. They have also found correlations between mortality and sex and age. Very young and old people are more susceptible to sickness and death. On average women typically live longer than men, although women are more likely to have bad health. [17]
