I think it is only logical to assume that, barring some unforeseen tragedy, humans will live longer in the future than they do today.  Every year new technologies and medical advancements are made that make treating and curing diseases easier, thus resulting in a longer lifespan.  There is no guarantee that problems won't strike an individual, but on the whole I see no reason why humans can't expect to live longer in the future.

Our life span has been gradually getting longer.  I think that it will continue to do so.  We continue to develop better medical technologies and to know more about health.  The one thing that could reverse this, at least in the US, is the fact that we tend to be obese.

It stands to reason with medical advances that human lifespans will continue to get longer, though there may be environmental pressures like pollution that push against that trend by contributing to cancer and other diseases. It is also the case that more sedentary lifestyles may lead to more diseases. Overall, though, it seems to me that the average healthy person will be able to expect to live longer in the future.

I think statistical trend over history and ongoing trends in medical science suggest yes. Clearly each individual is different but I think the overall lifespan is likely to increase, barring some unforseen world wide catastrophic event that would greatly decrease the popluation and destroy the technology that allows us to live longer. However to me that sounds more like the plot of a bunch of movies I've seen than a likely reality.

I have to agree with the above posts. Statistically, humans have steadily lived longer for centuries. Adult life expectancy in America was between 70-71 years in 1960, and the upward trend has reached 78+ years by 2009. (Canada and Japan are even higher.) Compared with the 16th century, when high expectancy rates barely reached 50 years, it is easy to see that things like advanced medical services and proper diets will continue to push the trend even higher.

Although human life spans have been increasing, there is probably a natural endpoint to that process. The telomeres on the ends of our chromosomes shorten whenever a cell divides, and at some point they become too short and the cell stops dividing, meaning that renewal and healing slow down as we age. Some researchers have worked on developing ways to slow or stop the telomere shortening, but doing so in a human will likely increase the odds of that person developing cancer. So unless and until we beat cancer, we will probably not be able to use telomere therapy to extend life beyond its naturally ordained boundaries.

Some people live to over 100 now and remain healthy, while others break down as they approach the seventies and eighties.  I was shocked to learn that there is a 150 year old person!  Dr. Aubrey De Grey believes that people will eventually live to 1,000.

The British scientist sees a time when people will go to their doctors for regular 'maintenance', which by then will include gene therapies, stem cell therapies, immune stimulation and a range of other advanced medical techniques to keep them in good shape. (Daily Mail)

It strikes me as a use for the rich alone.  Most people probably will not be able to afford this.  Will humans live to 1000?  Maybe.  Should they live to 1000?  How would that change our culture?  Those are the questions I wonder about.

It is very likely that human life spans will continue to grow longer.  As medical science moves forward, we find news ways to treat, cure, prevent, and protect the population.  Unless there is some global catastrophe which damages our ability to continue with medical science as we are now, life spans will continue to increase.  More and more diseases will be cured or at least treatable.  Newer and better ways to live with incurable issues will surface.  We are already seeing medical trials for things like artificial limbs, cloned organs, and cures for diseases once thought incurable.

The article you cite does not say that there is a 150 year old person. It says that someone who is already alive will be the first person to reach 150, which is just speculation. The oldest living human currently is either 114 or 121, depending on which source you believe (the 114 year old is well documented, the 121 year old's birth records are not official).

Is human life will be long in the future or not?
 Why !!?

 

Yes, I think the life span will continue to get longer. The average span has increased over the years. The average now for a Caucasian male is 76 years. One could argue that advances in medical science are a major factor.

the life span of humans today is becoming much shorter than it was previously....this could be due to a number of reasons includg diseases even though doctors are coming up with new types of medication there are still severe side effects and our life styles are not so healthy any more!

A very interesting topic with posters coming with ideas about logivity through advanced medical care. On the other hand there are threats to life due to pollution, environmental effects, natural and human imposed catastrophes shortening the life. There are claims for life span to extend to 1000 years that coincide with the Quranic claims of Noah's life span who had been preaching for 950 years (His estimated to age could be 1000+ considering about 40 years before he started preaching and the life after the Great Flood that he lived). However no one has discussed the implications of the longer life span.

This world has limited resources that are rapidly depleting due to environmental changes. Global warming has triggered the climate change that. The mother nature has already taken over the control and is rather annoyed with too much human intervention. So even if the the average life span extends significantly in future, it will have a very high price tag attached to it, not in terms of dollars but in terms of life of people. There would not be many people living on the globe. The sum of age of all the people living on the earth at any instant will be be much lower than the what it is today. Many would have perished before we reach a signicant increase in life span. The growth trend of native population in many countries of the west already exhibit this.

I doubt it due to degredation of telomeres. You can extend human life away from diseases and cancers, but age can't be stopped you do eventually shut down. With that said, you never know with future technological developments down the road.

if we talk about the life span of human beings and the science developing around us there is a possibility that human life span can be long in future. due to developed medical facilities and modernized  health care techniques. new ways of proctecting ourselves come into light and we have also heard that there are some kind of diseases which has been completely eradicated  but at the same time with growing population of world it becomes difficult to compensate the loss of land for agriculture and thus food production becomes less, this again harms human heath and indirectly their life span and also we cannot ignore the pollution which affects our health so a question regarding human life span cannot have definite answer till we are able to eradicate all the negative ponts which hinders this

It will get longer! Most probably, especially for developed countries. However, as developed countries get more and more developed and their life expectancy increases, the less developed countries are disadvantaged. They are more likely to become poorer and poorer, naturally leading to lower life expectancies.
