"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.
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 .
The study tracks trends in their death rates and life expectancy from 1990 to 2019, before the COVID-19 pandemic started. He says his projection doesn't mean that personal health choices are ...
Principles. The disposable soma theory of aging posits that there is a trade-off in resource allocation between somatic maintenance and reproductive investment. Too low an investment in self-repair would be evolutionarily unsound, as the organism would likely die before reproductive age. However, too high an investment in self-repair would also ...
Life extension is the concept of extending the human lifespan, either modestly through improvements in medicine or dramatically by increasing the maximum lifespan beyond its generally-settled biological limit of around 125 years. [1] Several researchers in the area, along with "life extensionists", "immortalists", or "longevists" (those who ...
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 ...
Now, a new tool called CheekAge offers a simple, noninvasive way to predict mortality by analyzing epigenetic changes in cheek cells. In their recent study, researchers found that CheekAge can ...
