Do unemployed people age faster?

Men who are unemployed for more than two years show signs of faster ageing in their DNA, according to a study published today in the journal PLOS ONE.

Researchers at the University of Oulu, Finland and Imperial College, London arrived at this conclusion by studying blood samples collected from 5,620 men and women born in Northern Finland in 1966. The researchers measured the lengths of telomeres in their white blood cells, and compared them with the participants’ employment history for the prior three years, and found that extended unemployment (more than 500 days in three years) was associated with shorter telomere length.

Telomeres are repetitive DNA sequences at the ends of chromosomes, which protect the chromosomes from degrading. With every cell division, it appears that these telomeres get shorter. And the result of each shortening is that these cells degrade and age.

Lust for life: breaking the 120-year barrier in human ageing

In rich countries, more than 80% of the population today will survive past the age of 70. About 150 years ago, only 20% did. In all this while, though, only one person lived beyond the age of 120. This has led experts to believe that there may be a limit to how long humans can live.

Animals display an astounding variety of maximum lifespan ranging from mayflies and gastrotrichs, which live for 2 to 3 days, to giant tortoises and bowhead whales, which can live to 200 years. The record for the longest living animal belongs to the quahog clam, which can live for more than 400 years.

If we look beyond the animal kingdom, among plants the giant sequoia lives past 3000 years, and bristlecone pines reach 5000 years. The record for the longest living plant belongs to the Mediterranean tapeweed, which has been found in a flourishing colony estimated at 100,000 years old.

Life expectancy and Fibonacci: Nature has designed us to live indefinitely

Posted by in categories: biological, biotech/medical, complex systems, futurism

After studying tables of current life expectancy (life expectancy increase per decade, in years, based upon United States National Vital Statistics) I found embedded a virtually perfect Fibonacci sequence. A Fibonacci sequence is a series of numbers as follows: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233, …etc, where each number is the sum of the previous two. See here for more details on the Fibonacci sequence: http://www.mathacademy.com/pr/prime/articles/fibonac/index.asp
To my knowledge, this has not been described before. This is important because, based on my ideas regarding Global Brain acting as a catalyst for promoting extreme human lifespans (http://hplusmagazine.com/2011/03/04/indefinite-lifespans-a-n…l-brain/), it may help us predict with some accuracy any dramatic increases in life expectancy. For example, the model predicts that the current maximum lifespan of 110–120 years will be increased to 175 in the next 20–30 years.

In simple terms, the fact that life expectancy increases in a certain manner, and this manner obeys deep-routed and universal natural laws, indicates that it may be possible to:
1. Predict life expectancy in the near future. Based on the Fibonacci sequence,
a 90 year old today, can expect to live another 5 years
a 95 year old can expect to live another 8 years
a 103 year old can expect to live another 13 years, then…
a 116 year old can expect to live another 21 years
a 137 year old would expect to live another 34 years
a 171 year old would expect to live another 55 years
a 236 year old would expect to live another 89 years
a 325 year old can expect to live another 144 years,
and so on.

2. Question the presence of ageing and death in an ever-evolving intellectually sophisticated human (who is a valuable component of the Global Brain). Based on current facts, the Fibonacci sequence with regards to life expectancy ends abruptly when lifespan reaches the limit of approximately 120 years. Why is this so? Why should a naturally extending lifespan deviate from universal natural laws? Life expectancy should continue to increase as an individual manages to survive to a certain age. The presence of ageing and death could therefore be considered unnatural.

3. Support the notion that ‘you need to live long enough to live forever’ (see Kurzweil
http://en.wikipedia.org/wiki/Fantastic_Voyage:_Live_Long_Enough_to_Live_Forever, and also De Grey’s ‘Longevity Escape Velocity’ suggestions http://www.ted.com/index.php/talks/aubrey_de_grey_says_we_can_avoid_aging.html).
