STREAM OF ANTI-AGING MOVEMENTS. "In 1976, futurists Joel Kurtzman and Philip Gordon wrote No More Dying. The Conquest Of Aging And The Extension Of Human Life. In 1980, Saul Kent published The Life Extension Revolution. In 1983, Roy Walford, a life-extensionist and gerontologist, published a popular book called Maximum Lifespan. In 2003, The Immortal Cell: One Scientist's Quest to Solve the Mystery of Human Aging, by Michael D. West was published." https://lnkd.in/dSjbPFq View in LinkedIn

HUMANS have devised every snake-oil, potion, cream, elixir, serum, pills and similar nonsenses to try and stop the effects of aging, probably from time immemorial. These have given the topic of aging a bad reputation. But the reality is that if you examine nature, there are surprising examples that lead one to believe that aging as humans know it is neither hard-wired nor inevitable in living beings, that is, for some, at least.

QUANDARY. "It appears that species do not age, even though they are composed of individuals whose somatic and germline cells have aged." http://www.publish.csiro.au/?paper=RD14514 View in LinkedIn

PROGENY OF AGED GERMLINE. "What is impressive is that older and older parents continue to have offspring that are nearly as pristine as those of younger parents, even though their germline cells have continued to age. Although the offspring of old parents are not as fit, on average, as those of young parents, differences are small and, in some species, compensated for by superior parenting with accumulated experience." http://www.publish.csiro.au/?paper=RD14514 View in LinkedIn

SPECIES DAMAGE SURVIVAL. "Another major force appears to be evolutionary pressure; individuals that best fit the environment out-reproduce those that fit less well." http://www.publish.csiro.au/?paper=RD14514 View in LinkedIn

TWOFOLD COST. "Now sexual reproduction not only confers benefits but also comes with costs. This includes the well known so-called twofold cost of sex. In most sexual cycles it takes two parents to produce one offspring, resulting in only 50% of any given parent’s genes being transmitted to a progeny. This is contrasted with asexual mitotic reproduction in which one parent can produce one progeny, and in which 100% of the parental genes are transmitted to the progeny, thus resulting in a twofold cost of sex vs. mitotic asexual production of progeny. http://www.mycologia.org/content/105/1/1.full View in LinkedIn

MEDICINE AND NUTRITION has shifted the Preston Curve. "Further significant finding of Preston's study was that the curve has shifted upwards during the 20th century. This means that life expectancy has increased in most countries, independently of changes in income. Preston credited education, better technology, vaccinations, improved provision of public health services, oral rehydration therapy and better nutrition with these exogenous improvements in health." https://lnkd.in/db2auRq View in LinkedIn

COST OF SEXUAL REPRODUCTION. "Sexual reproduction carries high costs: First, all else being equal, an asexual population has a twofold advantage in fitness over a sexual population in which males contribute nothing but their genomes to the next generation – the “twofold cost of males”." https://lnkd.in/es2qrc5 View in LinkedIn

RADICAL MODERN LIFE EXTENSION. "So far as we know, the last hundred years have been the most radical period of life extension in all of human history. At the turn of the twentieth century, life expectancy for Americans was just over 49 years; by 2010, that number had risen to 78.5 years, mostly on account of improved sanitation and basic medicine." https://lnkd.in/df8W2j6 View in LinkedIn

HUMAN AND YEAST SEX SIMILARITIES. "These involve: (i) ploidy changes from diploid to haploid to diploid states, (ii) the production of haploid mating partners or gametes from the diploid state via meiosis which recombines the two parental genomes to produce novel genotypes and halves the ploidy and (iii) cell-cell recognition between the mating partners or gametes followed by cell-cell fusion to generate the diploid zygote and complete the cycle." http://www.mycologia.org/content/105/1/1.full View in LinkedIn
