Will humans ever extend their life span to 500 years or greater?
The graph of life expectancy in the U.S. has been pretty much linear, going from 71 years to 78 years 1970-2010:Do we see just a hint of some plateau over the last few years? Maybe ... But look at Japan's curve, since it has the longest life expectancy of any major country in the world (thanks to Prof. David Roper): Their curve definitely seems to be flattening as it approaches 85 years (it's almost there now, actually).You can see almost the same thing in Germany:A lot depends less on medical science than on prosperity. It has taken a while for the eastern part of Germany to approach the life expectancy curve of the western part of Germany, but since unification in 1990, they are almost at equity now:So barring unexpected breakthroughs, I think we in the U.S. can also expect to reach a "natural" limit of 85 in 2040 or so (unless we really want to keep people in poverty, as some are advocating).This apparent physical limit may not be so different from athletic performances, which are plateauing as well. For example, the world record for running a mile:But then ... sometimes super humans come along and change everything:... and look like this:
What would happen if humans had a 400 year lifespan?
This will happen.It will happen in the following stages, and the first stage is well under way.CyborgsFirst we will all become cyborgs. This means that most parts of our bodies can be augmented or replaced as they wear out. It is likely that the first person to reach 150 is alive today.It is almost certain that the age of 200 will be reached this century, and death will more likely be due to accidents, or choice.AutomationIt takes less than 10% of the workforce (not the population) of a western country to produce all the essential products and services needed for survival. That is, the energy, transport, housing, clothing, food, and emergency services etc.We already produce more of just about everything we need, but much is wasted due to bad distribution, and legalities.The keywords of 'Better, smaller, faster, cheaper' apply to most technical products today, and convergence leads to our becoming walking data centres.This in turn leads to much of our work being automated, so our actual working week will be reduced to hours, and in some cases eliminated. A large part of the population will never work to earn a living, but work as part of community projects or in entertainment.PoliticsSociety will take the form of 'Tribes' with groups formed on the basis common interest, rather like having a 'Quora tribe'.Quorans will speak face-to-face, and collaborate on common interests.To some extent the tribes will be self-governing, and only need the authorities to cover the legalities.PopulationAlthough the global population is still growing, families are getting smaller. It is likely that the global population will start getting smaller this century, and stabilise with families having 2-3 children.There will be less need for cities so the population will spread and go to places that are currently sparsely inhabitied due to distance or hostile environment.Women will not require men for direct fertilisation, and in fact hardly need them at all in the traditional sense of husbands, so relationships will be based on factors of companionship.EntertainmentWe will not be bored. We will have the time and resources to do just about anything we want to do. Check out Wimp.com to see some of the things that people do when they have plenty of time.In all, the idea of living to 400 is not far out. There are quite a lot of living things that have lives well in excess of this now.
What will be the biggest benefit for human beings from mapping the human genome?
Knowledge is power. Expanding our knowledge of humanity's basic components will potentially help medical professionals understand and cope with a variety of biological enemies, such as cancer and detrimental genetic conditions. Further, deeper understanding of the disease processes at the level of molecular biology may determine new therapeutic procedures. This is the greatest benefit that can come from increased knowledge of the human genome... Molecular Medicine: •Improved diagnosis of disease •Earlier detection of genetic predispositions to disease •Rational drug design •Gene therapy and control systems for drugs •Pharmacogenomics "custom drugs" Technology and resources promoted by the Human Genome Project are starting to have profound impacts on biomedical research and promise to revolutionize the wider spectrum of biological research and clinical medicine. Increasingly detailed genome maps have aided researchers seeking genes associated with dozens of genetic conditions, including myotonic dystrophy, fragile X syndrome, neurofibromatosis types 1 and 2, inherited colon cancer, Alzheimer's disease, and familial breast cancer. On the horizon is a new era of molecular medicine characterized less by treating symptoms and more by looking to the most fundamental causes of disease. Rapid and more specific diagnostic tests will make possible earlier treatment of countless maladies. Medical researchers also will be able to devise novel therapeutic regimens based on new classes of drugs, immunotherapy techniques, avoidance of environmental conditions that may trigger disease, and possible augmentation or even replacement of defective genes through gene therapy.
Will sperm motility vary in 3 months ????????
hi I am 31 years. We are trying to concieve for 2 years. I have a semen analysis done on 07/27 and the report said that I have motility 36% in that rapid linear progression is 3% and the slow non linear is 33% (abstinance period is 15 days). I have taken fertility supplement for 3 months and I have done another semen analysis on 10/26 and the report says that motility rate is only 18% in that rapid linear progression is 0% and slow non linear progression is 18%(abstinance period 3 days) I want to to know what is the reason for the great difference between two reports. please help.
Is it possible for human beings to live more than 150 years?
The simplest answer is yes, it is very much possible in the near future. Advanced science and technology has enabled us to go beyond what our older generations could not dream of. For a person born in the year 2100, life expectancy estimates had a median of 100 years and a mean of 292 years.There are multiple areas of research in the field of anti aging: Gene Therapy, Stem Cells Therapy, Tissue Engineering, Thermal Aging, Young Blood Replacement, drug - Rapamycin..and so on. The technology giants( like google) are investing heavily on anti ageing research and development company.From the best of all scientific findings, -”the Telomerase” and “Senescent” are the most promising ones so far.Each human chromosome has telomerase at the end, which shorten with age. And with the increase of telomerase, life expectancy increases. This is already experimented on rats and has successfully increased their age by 40%. However, injecting telomerase has an increased risk of developing cancer with humans and the research is on going. But there is a confirm finding that the more chronic stress you are under, the shorter your telomeres will become, meaning the more likely you were to fall victim to an early disease span.Human beings start with one cell and the cell divides itself over the years of human life. At some point the cells stress out and stop dividing itself that is the end of species. There are some self-dividing cells that drives ageing are called as Senescent. If we can remove these Senescent cells, we can stop ageing. However this is also under development.Even with the combined effort of science and technology discovers an anti aging pill, you will need to survive long enough to receive the pill that will give you a further 30 or maybe 50 years.The most amazing anti ageing factors we know so far are: exercise and good food habits. Through this, it is possible to make people youthful and healthy for a longer period of time than being old and sick for longer. I would say- the problem in life is not the lack of medication, the problem in life is that we don’t use what we already know healthy.Regards,Pankaj JenaCertified Holistic Health Coach(Weight Loss Expert)09133085153 /+91 08374751515(Whatsapp)LoseIsGain@outlook.com / LoseisGain@gmail.com
How long can people live 50 years from now?
In my research of this topic which I have been conducting for several years now, I have discovered the following:Drugs exist TODAY that can extend the average persons life span by 20–30%. This also will delay the onset of age related diseases by the same amount.Within 50 years it may be possible to extend the lifespan of the average person 500 years using genetic therapies and other drugs.Within 100 years the average lifespan could be 1000 years using more advanced forms of genetic therapies and nano-technologyThese figures apply only to the developed world. Third world countries will not have these technologies available to them, at least not at the same quality/level.Governments are realizing that healthcare costs will be reduced by orders of magnitude if you can put off the effects of age related diseases as long as possible. Also, it is much more efficient to have each taxpayer pay taxes for a longer period of time (maybe centuries longer) and thus having a longer lifespan to aggregate the costs of education, healthcare, etc.This also has the effect of reducing or eliminating the population decline we are just starting to see in the most developed countries (Japan, Sweden, et al).I am 51. I have a slight chance to make 90–125. The odds are improving every day.
