Longevity FAQ

Human Immortality or Immortalism (from Latin immortalis ) is to extend human life or eternal life or achieving longevity. In general term Human Immortality also known as Longevity. But people always argue, raised questions and concerns about Immortality or Longevity or a possible cure for aging. Here is common questions and answers:

1: Aging is natural and so we should not fight it

First of all, and contrary to popular belief, aging is not universal. A number of complex species, such as lobsters, rockfishes, and tortoises, do not show signs of aging. Therefore, aging is not a prerequisite to life. Aging is neither inevitable nor universal.

Secondly, humankind is, in a sense, a struggle against Nature. We have antibiotics and vaccines because we do not want to be sick, which would be the natural outcome in most cases. Cancer, AIDS, pneumonia, the flu and many other diseases are a part of Nature we try to fight as much as possible. Smallpox, one of the greatest killers in human history, was thankfully eliminated by modern technology. Yet some people who drive cars, take medicines, wear glasses, receive e-mail, watch television, and do not have to kill their own dinner argue life-extension is unnatural. No doubt life-extension can be perceived as unnatural but this applies both to taking antibiotics and to fighting aging. Slowing and eventually curing aging is a technological adaptation of humans and one that, like many others before, will make us live longer, healthier, happier lives.

Lastly, very few seem to oppose fighting the individual features of aging. In other words, aging entails a number of pathologies, like cancer, heart disease, stroke and neurodegenerative diseases, whose cure is widely seen as desirable. Similarly, aging involves increased frailty and debilitation as well as functional declines of many types (e.g., declines in senses like audition and vision, and cognitive decline); research into how to delay and stop these is no doubt seen as positive. Therefore, it seems that fighting the individual components of aging raises little opposition yet fighting them all together raises discording voices and is seen as unnatural. As discussed elsewhere, targeting the aging process as a whole makes more sense than targeting age-related diseases and changes one by one. But the end result will be the same whether we cure aging by curing it as a whole or by targeting its features one by one. And it will still be an unnatural outcome.

2: What is the point of extending life (achieve Longevity or Immortality) if we are old?

This is a common misconception about research on aging known as the Tithonus Error: In Greek mythology, Tithonus was a mortal who was granted immortality by Zeus but was not granted eternal youth. As a result, Tithonus became increasingly debilitated and demented as he aged. To make it clear: extending life without quality is not what I aim to do. The ultimate goal of my work and that of many biogerontologists is to preserve and extend health, well-being, and life, not age-related debilitation. We aim not just to make elderly people live longer but–by improving their health–diminish, not extend, their suffering. In other words, what we want is to find ways to extend healthy lifespan by postponing disease and degeneration. Ultimately, we would like to find a cure for aging, an intervention that permits us to avoid aging and all pathologies associated with it, such as Alzheimer’s and Parkinson’s disease, heart disease and cancer. More than improving the quality of life of the elderly, we want to avoid having elderly people in the first place or at the very least minimize the suffering caused by age-related diseases.

Numerous studies have shown that extending healthspan is possible in model organisms, for example via caloric restriction. There are also reasons to believe that healthy lifespan can be manipulated in humans. For example, studies have shown that the older an individual gets, the healthier he/she has been. Centenarians, for instance, are more independent and suffer from fewer ailments than normal people do. While lifestyle and environment are important, there is ample evidence that genetic factors play a key role in longevity, as detailed elsewhere, and in centenarians living as long as they do. Therefore, identifying and understanding the genes and pathways underlying healthy aging in humans may permit us to develop interventions, including drugs, that preserve health and extend life. In the long-term, though more speculative, we may be able to cure aging using a variety of biotechnology approaches, as discussed elsewhere.

According to calculations, if we were to cure aging this would result in an average lifespan of at least 1,200 years in industrial countries. This assumes one would be forever young in body and mind. People would still die from accidents, infectious diseases, etc. After all, children and teenagers die too even though they are not yet aged.

3: A finite lifespan is best enjoyed

The ancient time average longevity of 19 years and I am pretty sure we are happier than them now. In fact, longevity increased 50% in the past century and in spite of that quality of life has clearly improved. Entertainment evolves and social adjustments occur. A cure for aging would not mean an eternal life for one could still die. It would mean an average lifespan of 1,200 years, but life would still be finite. In addition, people would always have a choice to end their lives–or avoid anti-aging treatments for that matter. I am a strong believer in personal freedom and choice and would never think of forcing an anti-aging treatment unto others. At present we do not have a choice of living past 122 years, which is the longest anyone has ever lived so far. With a cure for aging each of us would have a choice to live 100, 200, 1,000 or even more years.

4: Not everyone would benefit from a cure for aging

The issue of justice and equity is commonly raised when arguing against life-extension. Of course it is impossible to predict the price a fictitious cure for aging would have. From experience, we know that a number of medical breakthroughs are not immediately available to everyone. The early antibiotics were available only to an elite and a number of present technologies, such as CAT scans and heart transplants, are not available to everyone. That is not a reason for us to ban pacemakers or regenerative medicine. We do not deny heart transplants just because they are not accessible to everyone. We cannot deny health and life just because some people lack healthcare. Besides, even if curing aging is initially expensive, with mass production one can speculate that it will eventually be available to everyone at affordable prices, at least in industrialized nations. This at least is the general trend in other medical breakthroughs of widespread appeal. Curing aging will likely also be incremental rather than a single breakthrough, as discussed elsewhere.

5: Economic disaster would result with the collapse of healthcare

No, of course not. In fact, curing aging and extending healthy lifespan would be profitable for nations. The economic value of increased longevity from 1970 to 2000 was estimated at $3.2 trillion per year for the US alone through greater productivity and lower healthcare costs; economic benefits from future health improvements have also been estimated to be large. Presently, the greatest burden on healthcare comes from the elderly and the trend is for expenses with old age to increase as the percentage of people over 65 years-old rises worldwide (UN Programme on Ageing). If aging is not tackled, societies in the 21st will consist of a large proportion of frail, elderly people, which will result in a serious financial burden. Therefore, curing aging would be economically sound. People would live longer but also work longer and thus be more productive. Without the declining years of old age, healthcare and the economy would benefit significantly from a cure for aging.

6: Overpopulation would lead to a global catastrophe

When thinking about life-extension it is intuitive to consider overpopulation as a major problem. In the 1970s there was a current of thought known as the Mathusianism that predicted major problems due to overpopulation by the year 2000. These predictions failed miserably because their proponents did not take into account technological progress made in agriculture, transportation, etc. Therefore, we cannot see breakthroughs in aging research as isolated events but rather consider these in the overall evolution of the social organism. The world’s population increased almost four-fold in the past century and yet today we have a life quality unparalleled in human history. It is also important to point out that population growth with a cure for aging should still be slower than during the “baby boom” of last century; it will take decades for the demographic consequences of a cure for aging to be significant, meaning we will have plenty of time to adapt.

Although overpopulation issues are often overrated, no doubt curing aging can lead to new challenges due to faster population growth. Overpopulation in some regions of the world, such as Southeast Asia, may be aggravated by a cure for aging. The ecological consequences of human activity and negative impact on biodiversity may be augmented if we cure aging, even assuming technological progress in other areas. But then what is the solution? Controlling birth rates, even perhaps regulating reproduction as it happens in China’s “one-child policy”, may be necessary, though that poses other social and ethical problems. Crucially, letting people die to control overpopulation is morally repugnant. If we cure aging and overpopulation becomes a problem in some regions, then we must find other solutions besides letting people die by refusing medical treatment. Likewise, clearly some of the earth’s resources are limited, but if our species is using limited resources in a non-sustainable manner then this must be addressed whether aging is cured or not.

Overall, catastrophic overpopulation concerns due to a cure for aging are exaggerated. Curing aging may aggravate overpopulation issues in some regions of the world, but this will take decades and must be considered together with technological advances in other areas that are impossible to predict. Fears of overpopulation are not a valid reason to reject curing aging, or any other medical breakthrough that extends lifespan for that matter.

7: We should have other priorities on earth

Clearly, there are many problems and injustices in our world. Many nations face war, hunger, poverty, and epidemics. This does not mean industrialized nations must abandon expensive medicines. Besides, more often than not the problems of third world countries are political, not technological. For example, hunger is usually caused not by a lack of food per se but rather by the inability to deliver food due to war, anarchy, tyranny, etc.

Aging is the major problem we face in modern society. It is or will be the major cause of suffering and pain for me and the ones I love. This holds true for most nations nowadays and that is why fighting aging must be a top priority.

8: Overall, curing aging is ethically wrong

Not so. According to the principles of bioethics, like the principle of beneficence, since curing aging would benefit people, not harm them, it is not ethically wrong. Anti-aging therapies would lead to the amelioration of the many diseases for which old age is the major susceptibility factor. On the contrary, having a cure for aging and refusing to make it available to patients would result in pain and injury, clearly in contradiction with the principle of nonmaleficence. Even if we cure aging, individuals will still be able to choose whether they wanted to age or not, in accordance with the principle of respect for autonomy. If someone wants to continue aging despite a cure for aging being available, no-one can force him or her not to age and, as mentioned above, I am a strong advocate of personal freedom. Likewise, if a cure for aging is proven safe and efficient then it should be available to all of those who wish to benefit from it.
