"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.
The endurance running hypothesis is a series of conjectures which presume humans evolved anatomical and physiological adaptations to run long distances [1] [2] [3] and, more strongly, that "running is the only known behavior that would account for the different body plans in Homo as opposed to apes or australopithecines". [4]
In the original study, athletes using this method trained 4 times per week, plus another day of steady-state training, for 6 weeks and obtained gains similar to a group of athletes who did steady state training (70% VO 2 max) 5 times per week. The steady state group had a higher VO 2 max at the end (from 52 to 57 mL/(kg•min)). However the ...
The reliability theory of aging is an attempt to apply the principles of reliability theory to create a mathematical model of senescence.The theory was published in Russian by Leonid A. Gavrilov and Natalia S. Gavrilova as Biologiia prodolzhitelʹnosti zhizni in 1986, and in English translation as The Biology of Life Span: A Quantitative Approach in 1991.
Life extension – study of slowing down or reversing the processes of aging to extend both the maximum and average lifespan. Also known as anti-aging medicine , experimental gerontology , and biomedical gerontology .
COVID-19 is the most obvious and convenient culprit, both for the absolute decline in life expectancy and the divergence between the experiences of the U.S. and its economic peers.
Support for this theory has been bolstered by studies linking a lower basal metabolic rate (evident with a lowered heartbeat) to increased life expectancy. [ 5 ] [ 6 ] [ 7 ] This has been proposed by some to be the key to why animals like the giant tortoise can live over 150 years.
The expectancy theory of motivation explains the behavioral process of why individuals choose one behavioral option over the other. This theory explains that individuals can be motivated towards goals if they believe that there is a positive correlation between efforts and performance, the outcome of a favorable performance will result in a desirable reward, a reward from a performance will ...
