The Jellyfish, Turritopsis nutricula, appears to have achieved immortality. It is possible that organismic death does not occur in this species.
The subject of immortality is very interesting. It has been explored exhaustively for thousands of years.
Take a second and ask yourself; Would you want to live forever?
As always, I have to tie this idea to my agenda here at WholeFed. I believe there is a large number of us who would not want to live forever, who believe that more is not necessarily better. That a life well lived is enough and the soul lives on forever. Then there are those of us that would take that deal, but with the guarantee that we would live forever in a healthy condition.
The main question I have is;
Would I be healthy?
Could I pick my age?
Could I pick the point in my life when I was at my peak?
“What does immortality mean to me? That we all want more time; and we want it to be quality time.” Joan D. Vinge
There is a win win situation here. Maybe you can’t live forever but you can take advantage of the current knowledge about the ageing process to live longer but more importantly to live well.
At the top of the research is Nutrition. There exist foods, in your vegetable section, that have been shown to promote longevity.
Life-extending substances are contained in Plant Based foods: Vegetables & Fruits.
There are some known naturally occurring and artificially produced chemicals that can dramatically increase the lifetime or life-expectancy of a person or organism, such as Resveratrol.
Phytoalexin is a natural compound that is produced by plants naturally, known as natural resveratrol. It is called natural resveratrol. This antibiotic kills off bacteria and fungi. Grape skins, mulberries, raspberries and cranberries are home to this compound.
Other benefits of this are that natural resveratrol aids the memory, increases the ability to exercise and is an anti oxidant of note. There is also a belief that it can assist the body in warding off retro viruses, herpes and HIV.
It is good for the function of the heart as it helps the blood to coagulate. This is because natural resveratrol limits the excess platelets in the blood. Aside from this, it has anti carcinogenic, anti-inflammatory and anti tumorigenic properties contained in it.
Telomeres appear at the end of chromosomes. Telomerase is an enzyme that maintains the integrity of the telomeres. Chromosomes are crucial to all the life functions of the human body. This enzyme is responsible for preventing damage or loss of genetic information during the process of DNA replication. Therefore, it replaces the sequences of telomeres and aids genetic repair. Therefore, it controls the lifespan of cells that divide.
It is also known to mimic the actions of a phytoestrogen. This comes from plants and is a compound.
Scientists believe that boosting the amount or proportion of a naturally forming enzyme, telomerase, in the body could prevent cells from dying and so may ultimately lead to extended, healthier lifespans. Telomerase is a protein that helps maintain the protective caps at the ends of chromosomes. A team of researchers at the Spanish National Cancer Centre tested the hypothesis on mice. It was found that those mice which were genetically engineered to produce 10 times the normal levels of telomerase lived 50% longer than normal mice.
In normal circumstances, without the presence of telomerase, if a cell divides repeatedly, at some point all the progeny will reach their Hayflick limit. With the presence of telomerase, each dividing cell can replace the lost bit of DNA, and any single cell can then divide unbounded. While this unbounded growth property has excited many researchers. If an organism can replicate its body cells faster than it would theoretically stop aging.
Late last year, a team at the Dana-Farber Cancer Institute in Boston published a Nature Paper in which they detailed the reversing of the ageing process in mice.
They targeted the chromosomes that reside within the nuclei of all cells, and specifically telomeres, caps at the tips of chromosomes. The telomeres protect the chromosomes from damage, but also shorten with age, until the cells are no longer able to replicate.
Professor Ronald DePinho and colleagues manipulated the enzyme that regulates these tips – known as telomerase – and witnessed dramatic results. Mice engineered to lack the enzyme aged prematurely, but when the enzyme was replaced, the mice appeared to rewind the clock.
