why do you say that our life span is increasing? there are so many deaths ooccuring in n early age because of?

Question

sickness, my mothers grandmother died at the age of 104.....so im saying that the lifespan is decreasing......???? im making a research study so please help me....

Answer 1

It's simple mathmatics...number of people by the age at which they died.

It's getting longer, fact.

Answer 2

First your need to understand statistics. Since no schools seem to teach math any more, it might be difficult. Mathamaticians are not concerned with you or your family. It is true that having long lived ancestors can mean you have a better chance of living long, BUT, you may have bad eating habits(or other bad habits) be living on a toxic dump site (or in a big city, even worse) or have other "at risk" factors. You are only one of 250 million.
Statisticians have looked at hundred's of years of births and deaths in the USA and the world and found that more people are living longer lives now than in the past. It has to do with averages and percentages. About 100 years ago, in the USA, most families (man/woman/children) had 3-5 children die before they reached 5 years. Men usually had 2-4 wives in their life time. Woman often had more then 1 husband in their lifetime. This was because of disease or accident, and in the case of women, many died in childbirth. Homes were unsafe, being mostly heated by burning coal or wood. Plumbing was primative and sewage was thrown in the rivers and polluted the drinking water. There were no antibiotics, no vaccines, no sterile surgery. Water was often contaminated, meat contaminated because of the lack of refrigeration, etc.
Going back to pre-Columbian years, the life span of most European men was 40-50 years and women 30-35. Very few made 65.
So yes, we are given the chance for a longer life,because of modern medicine, food and water processing and safe homes. But it is only a chance. If we overeat or starve ourselves, drink or drug our bodies, drive recklessly, etc, we become a statistic. If we live to be 114, which seems to be the upper limit of our species, we become another type of statistic.
By the way, your research is so much BS. You write like a 3rd grader and would know all of the above if you had paid attention in school or read a decent newspaper. All of the above is junior high school stuff.

Answer 3

Life expectancy has increased and is still increasing. As a matter of fact, the rate of increase is itself increasing. As much whining about the various methods we are using to kill ourselves, the statistics are clear that the US population is the healthiest in history.
World populations are generally getting healthier and doing so quickly. However, statisticians are concerned that the robustness of the general population may be hiding important disease statistics. In the US, the concern translates to the possibility that the extended lives of the great statistical bolus called the Baby Boom may overshadow encroaching weaknesses.
So, the actuaries now also keep track of DALY (also known as Lost Years) which is defined as the number of years prior to normal life expectancy an individual dies or becomes disabled. So, if the life expectancy of a male is 65 years, the DALY would be twice as much if he died at 45 than at 55. Even so, in most countries, the DALY is decreasing.
Despite all the health scares we have been subjected to in the last 20 or so years, none have panned out. But they still come. I myself worry that, in the US, our controlled environments are becoming "too antiseptic" leading to some unexpected and unwelcome health trends among the young. But that's a different question.

Answer 4

What do you mean by our lifespans ? Everyone's life span is diferent. The maximum life expectancy is about 120-130. It has always been that way for humans. Even if humans used to only live up to 45-50 on average a century ago. There are different factors that effect longevity. If two twins are seperated at birth. One is adopted by a well off family that provides him with everything. So that he doesn't have to do anything. He can expect to live longer than his brother who is adopted by some poorer family. Who have to mine in difficult areas underground. He may die prematurely in a work accident or die from labour or black lung disease. He would have lived up to the same age as his brother. If he had better living conditions. But, people are living up to the standard maximum life expectancy due to generally improved living conditions,medical treatment(vaccines),inporved nutrition,cleaner housing. That's it.

Answer 5

If you are referring to natural deaths then yes the life expectancy is increasing.
This is due to use of antibiotics (before ur great grandmothers time) and an increase in general medical awareness and capabilities.

Ur great grandmother was an exceptional lady and lived past the average age of death but EXCEPTIONAL means as it says, not normal- maybe (fortunately) you have been blessed with high quality genes but more likely than not your grandmother was alone in this trait.

this does not mean you are guaranteeed to live so long but there is a possibility.

in general; the lifespan of the human pop is increasing due to medical and scientific advances.

I could refer to my immunology notes about germ free life forms but its 3:27 in the morning.

(look it up "germ free life forms" if u r interested cos its worthwhile in the future)

im a second year bio student at strathclyde university in Glasgow, Scotland

This is all factual.

I guarantee that with medical advances we are prolonging our average lifespan.

No questions no doubts because research over a much longer period of time has proved and is still proving this fact!

Hope this helps

Answer 6

On average, lifespans have increased over the past few hundred years. Your grandmother (may she rest in peace) is not typical. Some people may live that long, they are rare. Most people die in their seventies or eighties of natural causes. Deaths by disease and accident do not normally cause a dent in the statistics, because there are so few of them (they are more reported, but they are uncommon), unless there is a world-wide pandemic, wiping out millions of people. Natural causes (heart disease, organ failure etc) still account for most of us. As i said in answering another of your questions, obesity-related disorders are on the increase, so much so, that they will affect the life span statistics (at least in Britain, I've heard). Particularly due to eating habits of children causing irreversible damage to there organs, leading to an earlier death than their parents.

Answer 7

in my opinion, our life span is decreasing because of what we have done to our planet. lots of accident happened due to man-made things, such as car accidents etc. we also made a lot of pollution so there are now bigger opportunities to get sick, it's like a biological warfare.

natural calamities such as those caused by typhoon are also our fault. we cut down lots of trees that should have been our protection. and lots more.

i believe that these things contributed to the shortening of our life span.
