Why there is difference in the age of living?
603093
any living thing by its interaction with the environment goes on accumulating toxins that ultimately result in death. Usually the animals with a high metabolic rate are the quicker to die, but they breed fast and can evolve faster, as there are many generations in a small time.\n\nall cells are genetically programmed to die. this time is different for different species

It's really as much about "emotional age" as physical age.  Other than that, it you get too many years difference the "universe" is different...different vocabulary, experiences, history, etc.  Generally, the close the better, but there are certainly exceptions to this.  USE COMMON SENSE!

Try looking on webmd.com or another medical site. I think they can live into their 50s but most don't get very old.

In hot climate countries middle age 4 man starts at 35 whereas in cold climate countries man starts at 40,cos man can live longer in cold climate rather than in hot climate.

A female, age 53,could outlive her  63 yr. old husband by 12 years.  This of course  doesn't take into account any pre-existing medical conditions.\nRN

Because their machinery is different.  It's just biology.\n\nMen have "refractory time" to factor in before they can "go again," which tends to get lengthier as they get older.

More important than age is height and body type.

Yes..definitely there is something called 'Generation Gap'.But it is a term given by humans only.The idea is to define the difference in opinion and views that emerges between an elder person & an offspring.This might be because of the reason that as the time changes, world get advanced day by day.Thus, the environment n circumstances which might be different at the time of elders, changes by the time of our next generation.But it can surely be overcome if we try for it.The only thing is to maintain an understanding level with the elder or youngster, so that the outlook of both starts matching.The understanding of facts is a must here.This might require compromises & adjustments and adaptations can take place gradually.Since the elder has experience of life,hence, his point shall be heard well.But as the situation gets different with time, therefore the elders must also try to get a little open minded, broaden their thinking spectrum and get adapted to the current environment.\nOn the whole, in order to cut-out this generation gap, both belonging to different generations, ought to give space to each other!

I would dispute the claim that we are physically healthier. Yes, we have long life spans, but is that due to our health or is it due to medical and technological advances? It seems, rather, that we're unhealthier. Look at the rising obesity rates, for instance. The world is overcrowded; as Wolfe says, we humans live in a behavioral sink and the result of said behavioral sink is similar to what happens in animal populations. Stress is magnified, destructive behaviors are rampant (drugs, alcohol, etc) and such effects are obvious in society.\n\nAnd then there's this paradox. In this ever-busy, ever-changing world and among the greater stress in pretty much all people, we live very cushy lives. If we were thrown back in time, our resilience might allow us to survive. Obviously, we'd have a hard time adjusting to a world without technological conveniences, but I would think that some of us might be glad for the change of pace, the change of scenery.

Even if we could travel fast enough and overcome the energy constraints, there is another problem: the person would not perceive any increase in life span. In that person's reference frame, the person would appear to age as normal and would experience the same apparent lifespan.

Because by the time you get to be fifty, you are SET in your ways and ideas and not easily changed. Because of this, it is hard for two fifty year old people to get together and work out indifferences. I know, I'm 47 and can't find anyone like me!

I believe it has something to do with the fact that, viruses such as pneumonia affect  the older (and very young) moreso than an adult in his/her prime because the immune system is weakened.  Either by age or because it is premature (as in with children)  As you grow older, your body weakens and is once again more susceptible to disease/sickness.

Well doll I don't know if you heard but 40 is the new 30, so don't turn in your convertible for the volks wagon just yet...The way I see it is like this: In many other countries your not old until you've reached about 75 80, and so these men and women who are 'middle aged' or close to it, don't necessarily see themselves in that light.  Now in America because things are changing everyday and things seem to be getting faster and faster but we get more out of shape and lazy because we have technology that does everything for us, Americans seem to have more health issues after thirty five (heart attacks, diabetes etc.).  But just because you're 40 doesn't mean you have to be 'old'. Renew yourself, use all the knowledge that you have obtained in your life so far and apply it, meaning do something different, do something you regretted not doing in the past (with in reason). I guess my answer to your question is that what happens after you turn 40 is that you keep living (I mean no one grows horns or get abducted by aliens once they turn forty, like forty isn't they age that all human beings get there first tail) chill relax, and live a little bit more than you did last year!!

It is well-established that the human brain has the capacity to take in an infinite amount of knowledge and information, far more than our 80 years of life allows.  It is also well-established that the human body is constantly repairing, renewing and replacing itself, and should go on doing so.  The human body, by design, should live forever and should be forever young. The  medical field cannot understand why it is not so. These two facts alone demonstrate that this life, logically, is not all there is.

Species matters more than age.

Hi, good question, Its always older people who make this remark, when you are young a day can be so long, and you really can`t imagine 20 or 30 yrs ahead, and also you tend to live for the here and now.\nas you get older middle to elderly age life dosen`t seem that long anymore,you are more aware of your own mortality,and leaves you are more aware also of what you could do or re-do if time was on your side.\nalso there are people who fight getting old and regret  the aging process, again some people have had such full meaningful lives and they too mourn the fact that time is robbing them of more of the same.\nmany are the reasons for saying life`s too short and we will all probably say it sometime in our lives, the important thing is too live well and have few regrets.
