All the countries will become like China and India in population. The economical problems will become severe. Natural resources of the world will be under lot of pressure as Infrastructure projects will be continuously increasing and industrial development will be horrible.

The existing earth will become hell. The social life will be poorest and of course necessity is the mother of inventions. Inventions may increase to ease the lives of people.

Interesting point. Probably there would be bionic heaven and hell on earth.

Certainly life is changing in all its aspects

There will be many changes, both on individual and social level.

1. Suppose that we live 500 years. Will our young ages grow proportionally, to let say 300 years? If so, there will be much more children from each person. Both longer lifetime and growing fertility will increase the Earth population from 7-10 billion (today and projection for 2050) to much higher level (maybe 20 billion in 2050 and 40 in 2100), that will be catastrophic for the limited resources on the Earth. There will be wars for resources, and few will live those biological 500 years.

2. Suppose now that the youth will end at age 50, and 90% of life people will live being old. No additional children, but due to reduced mortality the stock of global population will grow to 20-30-40 billion in a century, with growing fraction of old who need more medical care. Health sector will consume 50% of GDP, while there will be not enough food for all.

All the countries will become like China and India in population. The economical problems will become severe. Natural resources of the world will be under lot of pressure as Infrastructure projects will be continuously increasing and industrial development will be horrible.

The existing earth will become hell. The social life will be poorest and of course necessity is the mother of inventions. Inventions may increase to ease the lives of people.

Things will be dire difficult. The anticipated soaring numbers of our population is a great headache to many scholars. The distressing question on the minds of many scholars is 'How can we cope with our limited and ever depleting natural resources?'

Great question! Unfortunately, human being would never change even if you extend life expectancy to 1 000 000 years. Human will always will be human. This is one of the reasons why Einstein said that " The world will not be destroyed by evil people but by those who watch them." Things have gone so bad in the world that human beings should not be given opportunity to stay up 500 years! They will continue to destroy the planet (humans, space, ecosystem, environment, atmosphere, soil, forest, water, ocean, lakes, fresh water, animals etc) and to devise catastrophic weapons! The world is no longer safe.

To conclude, the forces of nature is yet to balance because of human activities!

I've seen animal studies that show that as life expectancy increases, for a given set of circumstances, the birth rate drops. In particular, I wish I remembered the details, a species of bird(?) on an island in the Canadian maritimes, with no natural predators, had a life expectancy much longer than their mainland cousins, and also a much lower birth rate.

So, if this holds true for humans (and I'm not sure why we should doubt it should, as it already holds true in the more developed countries), the results should be okay. People would work more years, so the economy should not suffer, and no more people should necessarily be unemployed or in retirement.

We are already seeing birth rates below replacement levels, we are already seeing longer life expectancies, and we are already seeing the retirement age being advanced, for the younger generations. In the US, it is 66 years for baby boomers, and 67 years for Gen Xers. So I really don't see why all the doom and gloom. Of course, the assumption has to be that people live a productive life for the extended duration, not just barely staying alive.

There will be about 25 successive generations living at the same time. Wide spectrum of the generations mentalities might cause several social problems.  

If the life expectancy increased as much as 500 or more years, there would first be a big social problem. Assuming that each person had a child by the age of 30, he would have at least 5 children in his long life; if not more, unless there is tight birth control.

Another problem would be that jobs would be saturated and there would be no retirement if these long-lived people are healthy and continue to work. There would be no change in the generation of work, because the new generations would not have jobs for many years or even centuries.

Another issue, would be the shortage of resources of all kinds

On the other hand, we should not forget the meaning that each one would give to his own life, probably less short-term value. I also think it would affect their motivation, desire to live and personal self-realization.

The least, they would have more time to learn various professions and develop multiple skills. Even feasible for the majority of those who still give their due value to life, enough time to contribute to society with significant contributions and great human impact.

We will all develop ingrained expressions of boredom.

Trouble is with ideas of extreme longevity, how do you prevent brain change and decay? Change the brain, you change the person.

The mother-in-laws and their daughter-in-laws would spend a 500 years great time!!!

How much evil and suffering could have been done by dictators like Stalin for 500 years, and how many new dictators would be in the world - I think it's better that people do not live so long.

Here are 20 topics from the articles on "human life" AND ( change OR future OR futurist) . Among them may be you will found some of interest.

Each topic is presented with 20 words and 20 phrases as it is done in these articles.

Reading these topics will require efforts from you, since this is not a coherent presentation, and each topic is a list of substances, methods, theories, cases, etc. associated with this topic. Try to be patient, in the hope that new hypotheses and thoughts will appear.
