"The first 1000-year-old is probably only ~10 years younger than the first 150-year-old."–Aubrey de Grey, 2005 [1]. In the life extension movement, longevity escape velocity (LEV), actuarial escape velocity [2] or biological escape velocity [3] is a hypothetical situation in which one's remaining life expectancy (not life expectancy at birth) is extended longer than the time that is passing.
Telomeres at the end of a chromosome. The relationship between telomeres and longevity and changing the length of telomeres is one of the new fields of research on increasing human lifespan and even human immortality. [1][2] Telomeres are sequences at the ends of chromosomes that shorten with each cell division and determine the lifespan of ...
Biological immortality (sometimes referred to as bio-indefinite mortality) is a state in which the rate of mortality from senescence (or aging) is stable or decreasing, thus decoupling it from chronological age. Various unicellular and multicellular species, including some vertebrates, achieve this state either throughout their existence or ...
Paraplegia, or paraparesis, is an impairment in motor or sensory function of the lower extremities. The word comes from Ionic Greek ( παραπληγίη ) "half-stricken". [ citation needed ] It is usually caused by spinal cord injury or a congenital condition that affects the neural (brain) elements of the spinal canal .
Longevity quotient. Longevity Quotient (LQ) is a simplified measure to enable normalized comparisons of various species' longevity. It shares some similarity with measures such as Intelligence Quotient. It originated with Steven N. Austad and Kathleen E Fischer 's 1991 paper on mammalian aging. [1][2]
October 9, 2024 at 4:30 AM. Life expectancy in humans not likely to increase much more, study suggests. Human life expectancy has potentially been pushed to the max, new research suggests. The ...
Hereditary spastic paraplegia (HSP) is a group of inherited diseases whose main feature is a progressive gait disorder. The disease presents with progressive stiffness (spasticity) and contraction in the lower limbs. [1] HSP is also known as hereditary spastic paraparesis, familial spastic paraplegia, French settlement disease, Strumpell ...
The researchers discovered that while humans have gained about 30 years of life expectancy over the 20 th century, improvements in overall life expectancy have slowed—and actually declined in ...
