Evidence for a Limit to Human Lifespan

Longevity

Scientists from the US claim that the human life span may extend only up to the maximum of 115 years. As published in the Journal Nature, their results were completed by examining more than 10 years of data on prolonged existence of humans.

They reckon that a few rare people may have the opportunity to live a long life, but chances are so poor that one would have to scrub ten thousand earths to search for a single 125 year old. However though few researchers have applauded the study, others have termed it as a miserable sham.

The average period that a person may expect to live has been rising unremittingly since the 19th century due to favourable conditions like vaccinations, safer methods of child birth and fighting against lethal conditions like cancer and heart related issues. The group in New York studied data from the database of Human Mortality and the demises of people significantly older than 100 years of age, typically one who has reached the age of 110 in countries like UK, Japan, US and France.

The data displayed a rise in expectancy of life were slowing down in those above 110 years of age and that the highest age of death had reach a state of little or no change after a period of rise and fall for a minimum of 20 years. One of the researchers from the Albert Einstein College of Medicine, Prof Jan Vijg mentioned on the BBC News website that in case of people over the age of 105 the progress they make is very less, which shows that they are possibly approaching the maximum point to human life.

For the very first time in so many years they have been able to view this, it looks like a limit span of life is of 115 years of age. It is near to impossible to cross beyond that age. We would require ten thousand worlds like earth to find a single individual in a particular year who will exists until 125, showing a very little chance.

The oldest person

The oldest person Jeanne Calment, whose age can be traced back by official documents, was 122 years of age when she passed away in the year 1997. The French representative symbol of longevity was given birth to before the construction of the Eiffel Tower and also came across Vincent van Gogh the famous painter. Since her nobody has gotten close to the age she lived for.

The director of UCL Institute of Healthy Ageing Prof Dame Linda Partridge proclaimed that a boundary to lifespan has to exist logically. But to source she said that even though the paper being very interesting narrates what is happening, it fails to describe the things that will occur.

The pick of those above 110 in the study were influenced by infection and malnutrition in their younger days tracing back in the nineteenth century. Only in 1980 smallpox was declared as eradicated. It was definitely very unique to what the present group of people being born in a particular period will go through, however it would then be somewhat negative as many children have turned obese and that could hamper lifespan.

Travesty

The 115 year statement is a lot for the director of the Max Planck Institute for Demographic Research Prof James Vaupel. He defined the study as a miserable sham and stated that researchers had in history determined the limit to be 65, 85 and 105 years only to be proved incorrect again and again.

He mentioned in this sorry series, the people convinced that there are forthcoming limits did not use demography and statistical strategies to test the theories related to the limit of lifespan, instead the subjugated pompousness, under  supplied methods and pretty displays to try to prove their assumption.

This study fails to add any knowledge scientifically as to how long one can live. It is very clear that experiments suggest that there is a limit to lifespan, which observe animals in conditions which are ideal. From the University of Illinois, Prof Jay Olshansky said that mice have the tendency to live for nearly a thousand days, canines for nearly five thousand days and humankind is reaching a natural boundary to life.

Stopping ageing? 

The ultimatum of dealing with ageing is that we have not advanced to live to great old ages. Millennium of natural selection has improved us to thrive, grow and procreate in our formative years. The consequences to our bodies 50 years from now or later, at ages we have not gotten to in our existence in history will be a side effect of the guidelines in our DNA that are vital in youth. Therefore, any trials to proliferate human life will need tactic beyond curing diseases and try to solve ageing at cell level inside the body.
