    I was wondering, how long would I live if I was born in 1998, which I was, depending on a number of factors:

    - That I am not killed by another human or accident
    - That I die of old age
    - The advancements in medical science
    - Advances in life expectancy rates
    - Advances in technology
    - Possibilities for computer simulation of the mind inside a computer, thereby suspending the mind for the entire lifetime of the computer (If this invention comes about within the next 80 years according to Moore's Law.

    In my own opinion there is no greater mathematical Principle than that which is x - x = 0. This shows that matter can be created from nothing as long as the total product of the matter's mass & energy equal exactly zero.
    The only question is, "Where did all that antimatter go?"

    Longer than you might think. According to wiki, Ireland's life expectancy for children born 2005-2010 is 76.5 men, 81.3 women.

    But. My husband came back from an appointment with a cardiologist the other day with some news. A girl born now in Australia according to his doctor has an anticipated life expectancy of 100 whereas wiki has Australia at 78.9/83.6 for the most recently born group. Either the doctor knows something the rest of us don't or he's counting life expectancy in a different way.

    But all of this really depends on the combination of family history and individual circumstances, and pure serendipity has its part to play as well. In my family, if you drop off the perch before you're 85, you just haven't tried. And that's been going on for a fair while. My mother is now a couple of weeks short of 88 and my dad died at 87. So my family is already on the upside of whatever life expectancy applies in the community at large.

    Life expectancy also depends on income. In some Western Europe countries (for instance Germany, France), life expectancy is decreasing for people belonging to the poorest categories, probably as a consequence of the crysis and of the reduction of public expenses.

    Diet, style of life, universal healthcare also have an important role.

    Not as much as you'd think at first glance. The most important thing affecting life expectancy in rich western countries is inequality. And, even more surprising, it affects life expectancy all the way up the income scale. The richest people in more unequal societies have a lower life expectancy than the same income group in a more equal society. ??!!?

    The outstanding text on this is The Spirit Level: Why More Equal Societies Almost Always Do Better - Wikipedia, the free encyclopedia by Wilkinson and Pickett. It's worth getting a copy.

    Here's a taste in Wilkinson's TED talk. Richard Wilkinson: How economic inequality harms societies - YouTube

    life expectancy can be evaluated on the basis of following two factors

    individuals genetic make up
    individuals ecological behaviour

    life is like any meter running very fast. you cant hold/conserve it in a place. but you can make it remain a bit longer based on above to factors.

    People get excited about longer life expectancy, but what is the quality of life parallel? Are we living longer or just longer than we should? I don't find the idea of living to 100 particularly exciting if I'm going to be one rung up from a veggie.

    That's only a problem if you suffer a devastating stroke or from Alzheimer's and a couple of other degenerative diseases that affect brain function. Unless you're already over 70, there are likely to be both preventive strategies and treatment options as you approach 85. At the moment, about 50% of people 85 and over show some signs of Alzheimer's.

    The most important thing is that you can have the brain signs of Alzheimer's without any symptoms or signs at all. The nun study shows that the biggest difference is in your education and intelligence/mental functioning before age 20. The autopsies find that nuns who have shown no signs or symptoms at all of Alzheimer's may have just as many, if not more, plaques and other brain features as others who were displaying obvious and debilitating illness.

    Researchers have also accessed the convent archive to review documents amassed throughout the lives of the nuns in the study. Among the documents reviewed were autobiographical essays that had been written by the nuns upon joining the Sisterhood; upon review, it was found that an essay's lack of linguistic density (e.g., complexity, vivacity, fluency) functioned as a significant predictor of its author's risk for developing Alzheimer's disease in old age. Crucial to note, with respect to this finding, is that the approximate mean age of the nuns at the time of writing was merely 22 years. Roughly 80% of nuns whose writing was measured as lacking in linguistic density went on to develop Alzheimer's disease in old age; meanwhile, of those whose writing was not lacking, only 10% later developed the disease.
    Overall, findings of the Nun Study suggest "that traits in early, mid, and late life have strong relationships with the risk of Alzheimer's disease, as well as the mental and cognitive disabilities of old age."


    http://en.wikipedia.org/wiki/Nun_Study

    So if you were well educated with a reasonable vocabulary at age twenty, your likelihood of developing Alzheimer's decreases drastically. Look after your physical health so that heart / circulation problems are lessened, and the chances of living the last years of your life as "a veggie" go down again.

    Education is vitally important for life span also.
    People with a tertiary degree on average live at least 5 years longer than their counterparts with no such advanced education.

    Of course, the degree is accompanied by lots of other lifestyle and social changes also.
