how many years can a human live at most?

Answer 1

No more than 120, I think.

Answer 2

The current world record holder just died a few days ago. You can read about her here: http://www.cnn.com/2006/US/12/11/oldest.woman.ap/index.html?section=cnn_latest

She was 116 years old

Beyond "natural" life there are some technological advances which show promise to extend life. For one, inhibiting the degradation of chromosomes in cells by telomerase, free radicals, xrays, mutagens, etc. Our bodies begin to breakdown because the genetic code becomes less conserved as we age due to enviornmental and genetic factors. Cells cannot fully reproduce the proteins in the same quantity and quality as we age.

Beyond extending life, one has to beg the question, "If you could completely control life expectancy, would you want to?" Sure people want to live forever (at least some do) however death is a part of our natural world and controlling it 100% would certainly disrupt the natural process here on Earth, eventually leading to overpopulation of the ecosystem, depletion of resources and ultimate death as a species. Unless of course we evolve to find new resources on other planets. Controlling death in a way would mark a new course in our evolution. Is it likely? Not really, considering making the old new again would completely rule out the need for death and birth, two cornerstones of what defines life itself. It would not be life anymore, but rather something else. Existence?

Answer 3

One of the longest living women died recently at 116. That is highly unusual though. The average is around 88 years with women living almost two years more on average than men.

But llook for medical science to make rapid strides in the next 20 years which raise that average age by at least 10 years.

Just by find a cure for cancer avg lifespan would increase about 6 years.

Heart disease another 6. AIDS a few more.

And funding for treating aging itself as a disease is increasing.

Many people believe that the aging process itself could be reversed within our lifespan.

Answer 4

I was watching a program once that said humans aree actually meant to live to 120, but that the things we do to shorten our life is why we live so much less. I believe the oldest woman ever was like 121 or 124

Answer 5

Everyone's fate is different. My fiance's great aunt just turned 102 this past summer. Some people just have longevity in the genes, other's are unfortunate. But I thought you woudl like this story. A woman in the Tennesee lived until she was 116 years old!! She just passed away. But what a life!! The link is below to that story in case you were interested.

Answer 6

Around 120 years

Answer 7

in geriatrics we teach the life span of a human is 120 years.

not to be confused with life expectancy (which can very by population and access to health care.)

It is thought that the life span may be related to the size of telomeres at the end of each chromosome. Animal species with longer telomeres live longer. To read more, look up "telomeres" in wikipedia.

Answer 8

well the eldest woman in the world just died a few days ago at the age of 116..now a woman in Spain holds the title at 115 yrs old..but the average person doesn't live past 100..

Answer 9

Depends on the person. Assuming no disease or genetic damage, a human will live until enough cells have reached the end of their functional life as determined by telomere lengths, then likely die of organ failure.

Answer 10

The oldest person ever was 122 years and 164 when she died. So for now at least it looks like 123 years in the maximum. That could change.

Answer 11

I would say 120 but that would not be comfortable some live to 100 and stay active. I am sure you will show me some that live longer. looking at the oldtestiment adam noah and so on I am sure they must have meausred years diferently ofr they have been getting longer over time.
