New Study Suggests There's a Limit To How Long People Can Live (go.com) 290

Posted by BeauHD from the age-is-just-a-number dept.
Life expectancies have risen in many countries around the world thanks to breakthroughs in medical treatment and sanitation in the last century. The maximum age of death has also increased. But as these numbers continue to rise, it raises the question as to how long can people live? ABC News reports: The record for the world's oldest person is 122 years and the odds of shattering that record are slim, according to an analysis published Wednesday in the journal Nature. In the new study, researchers [at the Albert Einstein College of Medicine in New York] analyzed mortality data from a global database. They found that while there have been strides in reducing deaths among certain groups -- children, women during childbirth and the elderly -- the rate of improvement was slower for the very old, those over 100 years old. Next they examined how old centenarians were when they died. The record holder is Jeanne Calment, of France, who lived until 122 years old. Since her death in 1997, no one has broken her record. The researchers calculated the odds of someone reaching 125 years in a given year are less than 1 in 10,000. They think the human life span more likely maxes out at 115 years. Some aging specialists said the study doesn't take into account advances that have been made in extending the life span -- and health -- of certain laboratory animals including mice, worms and flies through genetic manipulation and other techniques. The goal is to eventually find treatments that might slow the aging process in humans and keep them healthier longer.

As such, a person's greatness can be shown by his age; should he live to be a thousand years, he must have died a great man, and lived a great man to have the wisdom to continue so long.

        And all the days of Noah were nine hundred and fifty years: and he died.

        Noah was born pre-Flood. And if you follow the geneologies, they lifespans increasingly shorten with each successive generation; thus not an immediate effect but something that took a few generations to take in.

        Most of those you quote were Pre-Flood; however, that doesn't change the lifespan curve that occurred post flood. Abram (who could have known Noah as their lifetimes slightly overlapped) made it to 175 (Genesis 25:7 [biblegateway.com]). Joseph (3 generations later) only made it to 110. Genesis 50:22-26 [biblegateway.com].

        As with Death in Genesis 3, the shorted lifespan did not happen immediately. Could it have? Probably, but that would have had several major consequences:

        • Slower re-population of the earth post-flood
        • Inability to communicate the past to future generations using eye-witnesses that were able to fully establish what actually happened through numerous generations across the vast majority of the populace.

          • Literally taken, the first twelve chapters of Genesis could have been written by just three generations (Adam > Methuselah > Shem), all who overlapped each other more than 100 years and lived 500 years after the flood. Even without written language, it would be pretty easy to convey verbally, per most primitive cultures.

      The first time I read that, I thought the same thing...oh, people are only allowed to live to 120 years old now. But read the chapter again carefully, the phrase means that the flood was coming in 120 years. The 120 years is how long Noah had to build the ark.

      • Clearly the lifespan of humans was reduced, as you see people living 900+ years before the downgrade to 120 years, then afterwards, you see lifespans around 120 years. Whether or not the 120 years referred to both lifespan and time before flood, the lifespan results are logged as well.

    Nature doesn't want people (or any animal) to live past the point where it is producing offspring and launching them into the world. Most animals have been bred to die, because this is advantageous to the species as a whole.

    However, the limitations are largely artificial - we can see that some few animals are essentially immortal. Selective breeding in insects achieves dramatic improvements in just a few generations. IIRC, they tried this with fruit flies - by the simple measure of only allowing older and older females to breed - and they tripled the lifespan in just a few generations. Higher mammals have the same cellular machinery.

    Of course, as soon as anyone talks about selective breeding in humans, well... Even if we could experiment with selective breeding for longevity (perhaps something along the lines of Heinlein's book [wikipedia.org], it is a sure route to massive resentment and probably mass murder Apparently, if we cannot give a benefit to everyone, then we are not allowed to give it to anyone.

    • With large mammals, though, continued support of children that take a long time to grow is useful compared to insects. Still, you're right that it comes down to selective pressure. Once having our great-great-grandparents around helps our reproductive success then we'll start living longer.

    • There is absolutely no need for selective breeding with humans. It's not like we're suffering from a shortage of sustenance, no part of our population (at least where we could create a controlled breeding environment) is in any danger of being deselected for breeding due to a shortage of nourishment or shelter.
